1. UL listed for 200 or 230 amps with copper conductors
only.
For individual dwelling units as defined in NFPA 70 (NEC), in cases where
the transfer switch is between the service main disconnect and the lighting and
appliance branch circuit panelboard(s), NFPA 70 allows for a reductions in size of
the feeder conductors.
All other applicable requirements of NFPA 70 regarding conductor Ampacities
must also be adhered to. Always install electrical equipment to the requirements
defined by the authority having jurisdiction.
