Is 620.51(B) saying a platform lift must be a separate circuit? I'm unsure as to why an inspector wants a separate circuit for a 3a trickle charged DC battery driven platform lift. EI says" elevator sub code wants it". I spoke to DCA elevator safety and was told they ASME and 620 are something something bla bla bla I didn't listen. The persons opinion was 620.51(b)
