ECN Forum Forums General Topics of the Trade General Discussion Area APC wall mount Transfer Switch

Well, I haven’t been able to find anything in the UL white book that refers to the overcurrent protection used with these transfer switch type panels and the UL 1008 standard that is mentioned by the manufacturer doesn’t seem to address this either.
Now I’m also wondering how this fancy type of UPS/generator backup transfer panel would handle the bypassing of AFCI and GFCI circuit breaker protection on generator power any different than a regular GenTran or Reliance panel would. This is another reason I generally prefer an interlock kit or dedicated generator backup panel.
