Using a 3 phase RCD on single phase.

Question

I have a 3 phase RCD that I want to use on a single phase. Will the fact that 2 phases are missing result in constant tripping (or not resetting in the first place)? If so is there a quick 'link the terminals' type solution or do i need to buy a (stupidly expensive) single phase RCD. Any help appreciated

Answer 1

There's only one phase missing. Single phase has two hots. Go with the single phase RCD.

Answer 2

Depending on current required it might be cheaper to use a static phase converter (http://www.phaseconverter.com/static-con... or build your own   http://www.homemetalshopclub.org/project...  http://www.metalwebnews.com/howto/phase-...   http://home.att.net/~waterfront-woods/Ar... ........ but if you don't want to have 3 phase outputs then if you leave the 3rd phase wire unconected it should work  http://hyperphysics.phy-astr.gsu.edu/hba...
