The following table lists wire sizes. The wires used assume that they are 600V vinyl wires and the wiring
distance is 30m(98.4ft) max. If the wiring distance is over 30m(98.4ft), choose the wire size in consideration
of voltage drop.
To comply with the UL/C-UL (CSA) Standard, use UL-recognized copper wires rated at 60°C (140°F) or
more for wiring.
