ARI — Air Conditioning & Refrigeration Institute
FLA — Total Full Load Amps of Electric Heating Coils
Fuse — External Fuse Size Required Per Circuit
kW — Kilowatt Rating
MWG — Minimum Wire Gage
VEL — Velocity
*(U) signifies unequal kW per step.
NOTES:
1. Subcircuits are internal heater circuits of 48 A or less ampacity.
2. Minimum wire gage is based on 75 C copper conductors; 3 conductors per
circuit.
IMPORTANT: To avoid damage from overheating, coils must not be
operated at less than minimum airflow (cfm).
Minimum Cfm = Coil Face Area x Minimum Coil Face Velocity
3. Electric heat performance is not within the scope of ARI Standard 430
certification.
4. All ratings shown are at 60 Hz. To obtain kW ratings at 50 Hz when voltage
does not change, multiply the 60 Hz rating by 0.833. For example, a 6-step
heater in a size 32 unit has a rating of 119 kW at 60 Hz. To obtain the
50 Hz rating:
119 x 0.833 = 99 kW at 50 Hz
If the voltage also varies from that shown in the table, use the formula in the
following example to arrive at the correct rating at the new voltage before
multiplying by 0.833:
