CAUTION: When sizing the wire, you must follow the guidelines of the
latest revision of the NEC. NM-B wire is equivalent to “Romex” cable. SEU
is equivalent to service entry cable. For NEC type NM-B wire, you must
size the wire using 60C ratings per NEC article 326.
* Minimum overcurrent protection per NEC 424-3b not to be less than
125% of total amps for fixed resistance heat.
Table 9a. Electrical Specifications
** Alternate wiring combinations can be used. Refer to the latest revision of the NEC for these
appropriate alternate combinations.
