Is there a similar requirement in NFPA for disconnection times, maximum earth loop impedance and touch voltage as there is in BS 7671 (British standard 16th edition wiring regs)?
Specifically the BS gives guidance on fixed apparatus (5 second disconnection requirement), or shorter disconnection times for portable or handheld apparatus. Based on this a maximum earth loop impedance shall not be exceeded.
If there is an correlation for a similar requirement I would be grateful of the relevant code/section.
