Welcome to my blog. I document my adventures in travel, style, and food. Hope you have a nice stay! Low voltage landscape lighting is a breeze with the right fixtures and a plan to place them. Part 1 of our guide explains which materials you need, what kind of low voltage options you have, and a few tips on where to place your fixtures.
This post is step-by-step instructions for installing your lights. There are also these optional materials, which are dependent on your lighting layout or preferences:. Weatherproof cover for your GFCI outlet if your transformer is a plug-in model.
Wire clips and stainless steel screws for mounting cables to trees. PVC pipes, couplers, and caps to weatherproof connections to path lights. Your transformer should be centered in your layout in case you have to wire more than one line, i.
Your first fixture should maintain about a foot distance from the transformer to prevent it from getting too much voltage and burning out prematurely. Here are 5 general lighting layouts for landscaping:. The wiring is an easy, single run with lights located along the length of the wire. Split — Multiple series single runs wired back to one transformer is known as a split run. Split Tee — Basically multiple tee runs, all to one transformer. This layout can be tricky since you need to be extremely careful not to cross the wire, meaning mix up which wire end was connected to which wire on the load side of the transformer.

Load side transformer wires tend to be the same color and only connections from the transformer to the main are different insulation colors to denote the hot from the neutral wire. Multiple straight runs in several directions, a tee connection run, or a looped run are the recommended layouts to reduce voltage drop issues.
Allow about three extra feet of wire as leeway for when you begin to bury or splice your wiring. String the wire under or around obstacles like fences or shrubs. Try to run wire about one foot from the edge of a sidewalk or pathway.
Position your transformer close to where you will connect it to the main power.When operating low voltage lightsyou need a transformer to convert your standard line voltage V or V into low voltage 12V or 24V. This allows your lights to function properly. If you connect low voltage lights directly to line power, the higher voltage would cause them to burn out immediately.
The transformer makes them compatible, sort of like a USB adapter for your iPhone. To figure out how many lights you can power with a single transformer, look to the minimum and maximum wattage ratings. The transformer's minimum wattage rating tells you the smallest number of watts it needs to power in order to work. The maximum wattage rating, as you probably guessed, indicates the largest total number of watts a transformer can handle.
There are two kinds of transformers you can use — electronic and magnetic. Electronic transformers are cooler, quieter, and more compact than magnetic transformers.
But, electronic transformers can't power more than watts, while magnetic ones can power as much as 1, watts. When using an electronic transformer, the total wattage of the light fixtures connected to the transformer should be less than or equal to the maximum wattage rating. This is because the cheaper design of many magnetic transformers can cause additional power loss. So, if you want to connect eight landscape lights to an electronic transformer, and the lights use 20 watts each, you would need a watt transformer.
If you want to connect ten landscape lights to a magnetic transformer, and the lights use 30 watts each, you would need a watt transformer.

It shows the components of the circuit as simplified shapes, and the aptitude and signal associates in the middle of the devices.
A wiring diagram usually gives guidance just about the relative approach and understanding of devices and terminals upon the devices, to support in building or servicing the device. A pictorial diagram would be active more detail of the monster appearance, whereas a wiring diagram uses a more symbolic notation to make more noticeable interconnections more than instinctive appearance.
A wiring diagram is often used to troubleshoot problems and to create clear that every the links have been made and that anything is present. Architectural wiring diagrams fake the approximate locations and interconnections of receptacles, lighting, and enduring electrical services in a building.
Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be on a common circuit. Wiring diagrams use tolerable symbols for wiring devices, usually swap from those used on schematic diagrams.Cute ways to ask to hold hands
The electrical symbols not abandoned produce an effect where something is to be installed, but as well as what type of device is monster installed. For example, a surface ceiling roomy is shown by one symbol, a recessed ceiling lighthearted has a different symbol, and a surface fluorescent fresh has complementary symbol. Each type of switch has a swap fable and in view of that attain the various outlets.
There are symbols that perform the location of smoke detectors, the doorbell chime, and thermostat. A set of wiring diagrams may be required by the electrical inspection authority to take on board association of the habitat to the public electrical supply system.
Wiring diagrams will then attach panel schedules for circuit breaker panelboards, and riser diagrams for special services such as ember alarm or closed circuit television or additional special services. Ooma Wiring Diagram Wiring Diagram 56 views.Calculate sunrise sunset times excel

To control voltage drop in low-voltage landscape lighting systems, there are two things to consider. The first is having a multi-tap transformer to compensate for voltage drop by having several higher-voltage taps available. When utilizing a higher-voltage tap at the transformer, the voltage starts out high then drops down to the proper voltage as the power travels through the wire to the fixtures. There is really only one way to confirm that you are getting proper voltage to your light fixtures — by verifying and testing with a digital voltmeter.
Second, you need to be able to distribute equal voltage to every single fixture in your landscape lighting system, and that takes a well-planned wiring method. The only wiring method that can get equal voltage to every fixture is an equalized hub method of wiring. This method requires equal lengths of wire on all fixtures leading to a central connection point a hub.
There are many myths, misconceptions and falsities out there in the common understanding of voltage drop. No more voltage drop. To explain, take the following example: A truck engine is designed to run optimally at 2, rpm, but I run my engine at 2, rpm, and you run yours at 4, rpm. Both engines will work, but my engine running at 2, RPM may lastmiles or more. The engine running at 4, RPM may fail considerably sooner. Similarly, LED lamps have an hour rating of 20, to 40, hours, but not all LED lamps run at their peak performance.
Years of lamp testing reveal that changes in voltage decreasing and increasing the voltage affect the internal electronics and drivers in four ways:. Now, that being said, all LED lamps have some increase due to the electronic driver. Make sure you use a true RMS amp meter; this will ensure that you do not overload the wire, transformer or fuse. So the goal then is to get 12 volts to all LED lamps. Use a multi-tap transformer — they have been available for more than 20 years; and although we are using smaller-wattage transformers today to watts we should still use a 12, 13, 14, and 15 multi-tap transformer.
Or, what if your voltage changes from daytime to nighttime? This is a typical situation and happens all the time because we usually check voltage in the daytime when it is typically higher by 5 to 10 volts than at night.
The other big voltage drop killer is that we typically tap into an existing outlet, and the homeowner adds something to that circuit, thus causing voltage drop. How do you solve this issue? If you have a multi-tap transformer, all you have to do is change to a higher tap at the transformer, and the voltage will increase to the lamp.
The remaining fixtures get less and less voltage in sequence. The number of fixtures and the wattage of lamps along with the wire distance will determine the voltage disparity.
Sometimes in lighting designs, you are very limited on your wiring space. The one and only time a daisy chain method can be useful is when you mount fixtures above ground and out of the earth.
As soon as you put the system into the ground, you are asking for trouble with bad or poorly made wire connections.Peugeot 206 04 fuse box
There is really only one advantage to the daisy chain method, and that is when placing fixtures in hard-to-reach areas such as rain gutters, second stories and under fascia. There are many more disadvantages, including too many points of connection, time consuming install, difficult to troubleshoot, short wire leads do not allow for much movement at the fixture, and daisy chaining does not get equal voltage to all lamps.
One last point of concern with the daisy chain method is that generally every fixture needs splicing into place, creating the multiple points of connection expressed above. This greatly increases the potential of having a failed connection due to water infiltration, or a bad mechanical connection resulting in a heat buildup and melting of the wire.
Due to the large amount of potential voltage drop, you might also experience failing lamps and a poor-looking lighting job due to unequal voltage. The loop method brings the same voltage and power to both ends of the wire run. When using this method, the home run wire goes to the first fixture, other fixtures are then daisy chained while maintaining wire polarity very important.
A similar method is used in irrigation by double feeding the sprinkler zone to help equalize the water pressure throughout.Assortment of 12 volt relay wiring diagram. A wiring diagram is a simplified traditional pictorial depiction of an electrical circuit.
It reveals the components of the circuit as simplified shapes, and also the power and signal connections in between the tools. A wiring diagram generally provides details concerning the loved one setting and also setup of devices as well as terminals on the tools, to assist in structure or servicing the tool.
A photographic diagram would reveal more detail of the physical appearance, whereas a wiring diagram utilizes a more symbolic notation to emphasize affiliations over physical look.
A wiring diagram is typically utilized to fix problems and also making certain that all the links have been made and also that everything is existing. Click on the image to enlarge, and then save it to your computer by right clicking on the image.
A wiring diagram is a simple visual depiction of the physical links and physical layout of an electrical system or circuit. It shows just how the electrical wires are adjoined and also could also reveal where components and components could be connected to the system. Use wiring diagrams to help in structure or manufacturing the circuit or digital gadget. They are additionally useful for making repairs. Do It Yourself lovers make use of wiring layouts however they are also usual in home building and car repair.
For example, a residence builder will intend to verify the physical place of electric outlets as well as lights making use of a wiring diagram to prevent pricey blunders and also developing code offenses.
A schematic shows the plan and also feature for an electric circuit, however is not interested in the physical format of the cords.

Electrical wiring diagrams demonstrate how the wires are linked and where they ought to situated in the real gadget, in addition to the physical links between all the parts. Unlike a photographic diagram, a wiring diagram utilizes abstract or simplified forms as well as lines to reveal components. Pictorial layouts are frequently images with tags or highly-detailed illustrations of the physical parts. If a line touching one more line has a black dot, it indicates the lines are attached.
The majority of icons utilized on a wiring diagram look like abstract versions of the genuine things they stand for. As an example, a button will be a break in the line with a line at an angle to the wire, similar to a light button you can flip on and also off.
Landscape Lighting: Voltage Drop and Wiring Methods
A resistor will be represented with a collection of squiggles symbolizing the limitation of current flow. An antenna is a straight line with 3 tiny lines branching off at its end, a lot like an actual antenna.On the secondary side low voltage taps of the transformer, each circuit has its own magnetic circuit breaker toggle switch that is connected to a Common Tap marked with a label, "COM".
These Common Taps can accommodate up to W 25A. The exception to that is when the transformer capacity is less than W; in that case, the capacity will be equal to the transformer capacity. Generally, it is a good practice to connect each of your home run lines directly to the transformer, spreading them evenly among the available commons.
Ideally, if two or more home run wires share a voltage tap, then connect them to the same common. The home run cable e. One wire gets connected to the Common Terminal labeled "COM"the other wire connects to a Voltage Terminal the colored labels that say 12, 13, 14, etc. The correct Voltage Terminal is the one that results in an optimal voltage at the fixtures connected to that run. This is a Multi-Tap transformer, which means you can output at a variety of voltages to compensate for Voltage Drop see our learning area for more information on layouts and voltage drop.
For example, if you have a long run of feet you may need to use the 15v Voltage Terminal in order to have 12v of power all the way out at the far away fixtures.
You can hook up multiple home runs to each and any of the terminals. For example, you may have 6 home runs, in which case you would have 6 wires in the same COM terminal and the other half of the wires go into the colored terminals. To connect a home run wire to the terminals, split the paired wire down the middle to separate the two wires and strip half an inch of insulation off each wire.
One end goes to the COM terminal, the other into a voltage terminal. Loosen the terminal screws small flat head screw driver and insert the wire into the terminal opening which is located at the bottom 90 degrees from the terminal screw facing the bottom of the transformer. Tighten screw to secure wire s. Low voltage wire does not have polarity, it does not matter which of the two wire connects to the Common Terminal and which to the Voltage Terminal, as long as one wire goes to each.
Optional timers and photocells plug right into the transformer ports labeled and located inside the cabinet. It is easier to see and insert the wires into their terminals when the transformer is lying on the ground.

Most single family homes will have several outdoor power outlets installed. If you don't have an outdoor outlet, you will need to have an electrician install one.
Think about the layout of the lighting. It is important to plan ahead when installing low voltage lighting so that you can avoid any potential problems, especially with the setup. Make a plan for where you want the lights to go and think about what kinds and lengths of connecting wires you'll need a head of time so that you can purchase the right materials and ensure your project will go smoothly.
This step is important to help determine how much cord and what capacity transformer you'll need to buy. Draw the layout of the lights on paper, and take measurements outdoors to determine how much wire you'll need.
Lights can be installed in several different configurations. Pick an outlet that is out of view, if possible. The transformer will plug directly into the outlet, so it can be quite an eyesore. Try to pick an outlet that is on the side of the house or hidden by shrubbery. Depending on what kind of transformer you use, some must be mounted on the wall as well as plugged into the outlet.
So keep this in mind as well. Part 2 of Choose a transformer.
