Re: In Need Of 3 Phase Step Down Transformer

D4T,
Since your power center will be a distribution panel on the SECONDARY of a transformer, I strongly suggest that you and your CAMPER TECH STAFF, construct a driven grounding electrode system to provide the 'earthing' of your transformer's secondary NUETRAL.

Your electrical distribution system NEEDS to tied to ground to stablize the phase voltages and to insure a real return path to source exists at the time of ANY (including the FIRST) phase to ground fault.
