ECN Forum Forums Code Related Discussion NEC & other Code issues 16/3 SO Cord.

We're removing 500 watt resistance heaters from some instrument cabinets. The heaters are fed from a 20 amp circuit. 16/3 SO cord is routed from the supply to the heaters inside the cabinets. The same 20 amp circuit is going to supply new heat trace (120 VAC/ 3watts a foot). Can the 16/3 SO cord be used to connect to the heat trace? The splices will be inside a power connection kit (junction box). Thanks.

Mike;
depends how it's used, check 240-4, T400-5
