Powerstac Library: “SIG” Wire Combinations

When the SIG option is selected (providing an independent conductor for each circuit), more room will be needed to accommodate the additional wiring. Therefore the largest J-box or non-metallic conduit will be used, which may differ from your original selection. Note that this J-box may need to be externally mounted to the rack.
