To provide 120V input and produce 120/240V output you would need to have THREE 120V windings (at least), and a ratio of 1:1 between them. This transformer does not do that. There is one way to use that transformer to produce 120/240V from a 120V input, but it's not a conventional way to use that transformer: Connect the two 120V windings in The outlet is in a location where there are no nearby 120 V outlets and it would be convenient to occasionally to have 120 V there instead. Functionally it is possible with just a dryer plug, a 20 amp duplex outlet, and a box to create an adapter to convert (in the functional sense, not physics) the 240 V outlet into 120 V. You could also use an 'autotransformer' where you have two 120V coils. One coil is connected to your 120V L-N supply, the second coil is placed in series with the first to derive 240V L-N. Ground and neutral are direct from your split phase supply, the transformer generates the 240V terminal. 14442 posts · Joined 2015. #6 · May 15, 2016. Take three (3) single phase transformers -- of identical manufacture -- and wire them up, yourself. Each single phase transformer would be wound 347 to 120 turns. The 347VAC secondary would have 120 turns; the 120VAC primary would have 347 turns; each times the number required to handle the kVA There are a couple ways. Purchase a 240 volt heat lamp. Pull a new set of conductors that has a neutral, mount a small breaker box, and from that you would have 240 and 120 volt power. Run a new set of conductors to provide 120 volts. I would pull a new 3-wire 240 volt line buried in conduit. Mount a small breaker box, and have both. The way you get a 240-volt circuit is simple. A “double-pole” circuit breaker is clipped into both 120 buses at the same time, so the voltage to the circuit is doubled. That’s why 240-volt circuits need two hot wires and a neutral to carry the electricity to the appliance, plus a ground wire.

First, disconnect and cap off both hot wires and neutral, and go back and reset the GFCI breaker and see if it holds. If it does not hold, follow the diagnostic procedure, 110.3 (B) to get it to indicate whether it is an overload or GFCI trip. Troubleshoot problem with the cable. So it wouldn't matter if you got a big baseboard heater that is 120V, you couldn't hook it up anyway. Contrast with a properly wired 240V circuit, which can carry 3840 watts, or almost 3x as much, that is why baseboard heaters are mostly 240V. RCxr1f.
