Table 10 — Electric Heater Data
LEGEND
*Standard control steps are listed under the Control Step heading. “Free” additional
steps of control are optionally available when the number of subcircuits exceeds the
standard number of control steps.
†MCA = 1.25 x FLA; for proper wire sizing, refer to Table 310-16 of the NEC.
**2 control steps in this voltage.
††3 control steps in this voltage.
***4 control steps in this voltage.
†††5 control steps in this voltage.
NOTES:
1. Subcircuits are internal heater circuits of 48 amps or less.
2. Electric heat performance is not within the scope of ARI standard 430 certification.
3. To avoid damage due to overheating, minimum face velocity cannot fall below
350 fpm.
