How to install a Low Voltage Landscape Lighting Transformer | VOLT®


Hi, Tim from Volt Lighting again. Today we want to do a segment on how to install
the Volt transformer. Today we have a 300 watt transformer we are
gunna install. Installation is the same as the 6, 9, and
1200 watt transformers. So we will show you how to do it. You will need a few tools for this installation. A box of masonry screen anchors, and screws,
needle-nose pliers, a large flathead screwdriver, and a phillips screwdriver, a marking pencil,
a tape measure, and a hammer drill. Check the box size on your masonry anchors
and make sure you have the proper size drill bit. After you unbox the transformer, the first
step is to open the transformer door and remove it from it’s hinges. Now on the bottom of the transformer we need
to remove one of the half inch knock-outs so that we can place our wire up inside the
transformer. To do this I like to use and old screwdriver,
one thats been beat up and used for this before. Place the edge of the screwdriver on the outer
edge of the half inch ring and give it a good solid blow. Repeat this step until the plug is removed. Now the Volt transformer comes with three
different sizes of knockouts, a half inch, a three quarter, and a one and a half. With the half inch knockout removed we now
want to install the terminal adapter in the bottom of the transformer. With the half inch terminal ring clamp screwed
down, it makes the terminal adapter fit very tight. Set the transformer in the approximate location
where it’s gunna be hung. We need to have at least twelve inches of
clearance from the bottom of the transformer to the ground. Then take your pencil and mark the top hole. In the top hole that you marked go ahead and
take your hammer drill and let’s drill our hole about one inch deep. Then you can take your masonry anchors and
screw and go ahead and insert them in the hole and set them in place. Thread in your anchor screw now and leave
about an eighth of an inch gap so we can hang the transformer right on the screw. With the transformer hanging vertically, mark
the bottom hole. Slide the transformer aside and now drill
the hole for the bottom anchor sleeve. Put your masonry anchor and screw together,
put them in the hole and secure it down with the screwdriver. With the bottom screw in place you can now
secure down the top screw for the transformer. With the transformer in place we now need
to roughly measure how much wire we are gunna need to go up inside the transformer. Once you have that go and cut off the excess. Take your tape measure and measure the length
of the conduit needed. On some half inch PVC conduit, measure out
the length needed and cut it. You can use a pipe saw or you can use PVC
cutters like I’m holding here in my hand. Either one will work. Take the pipe you just cut and slide it over
the end of your wire. Now thread the wire up through the bottom
of the terminal adapter that we installed earlier and twist the pipe up into the socket. With the cable and conduit in place we can
now go ahead and backfill the hole at the bottom of the transformer. Lets review a few of the tools you will need
to wire this transformer. A pair of offset cutters is a great idea for
cutting wire, you will need and offset flathead screwdriver, the small bit size fits the screw
terminals on the transformer very, very well. Some wire strippers, these particular ones
are automatic strippers with wire size gauges that make it easy to identify the correct
knife size. Finally, if running multiple cables identify
each run with a different color tape. This is a good way to organize your system
layout. On the back of the transformer label the inside
of your cover with the color run, description, and wattage used. Now take your wire cutes and separate the
two ends of the wire and pull them apart. You want to take your wire strippers now and
expose about one inch of the cable. The majority of all VOLT transformers are
multi-volt units. Which means they offer voltage output that
varies in power from 12 volts to 15 volts. The higher voltage taps are used to overcome
voltage loss from high wattage loads and long cable runs. Begin by loosening the screw clamps on the
voltage lugs and twist the wire ends. One of the conductors will always be placed
on the common side, insert it and tighten it down. Take the other conductor now and place it
in the other appropriate voltage tap and tighten it down. It’s now time to install the control device
for your transformer. We’re using the Intermatic DT 620 astro-timer
for this installation. Simply remove the terminal plug from the transformer
and plug it into the receptacle on the timer. Now you just have to plug the timer unit into
the receptacle on the transformer and your transformers control device is installed. To reinstall the transformers door simply
line up the pins on the barrel sockets and slide it down into place. It should slip in pretty easily. Close and latch the door and plug the transformer
into a GFI receptacle with a weathertight box. If you have any further questions about the
installation of this transformer or any of the VOLT lineup products please give us a
