Wiring a large conference room with some countertop workstations. I am responsible for design and want to provide some isolated ground receptecals at the countertop work areas. Will be installing a new three phase sub panel in this room and am looking for most economical and efficient way to get a proper isolated ground circuit to these receptecals. Plan to serve panel with 4 wire SER cable - not pipe. Any way possible to come off this panel with isolated ground circuit or am I mandated to go back to main service panel. It is a long run and therfor I would like to avoid this. Also piping to this sub panel is really not feasible. Thoughts, suggestions, etc. Should I run Type AC cable from main service panel to receptacles or is there a better method?
Thanks for any help.
