## Step 1

Determine whether the electric heater has field-installed electric heat or has single point power (contains electric heat). The formulas for the two variations are different.

## Step 2

Multiply the full load amps of the indoor fan motor by 400 percent for a single-point power unit.

## Step 3

Add the resulting number to the full amp loads of the heater. This will give you the MOCP for a unit with single-point power.

## Step 4

Multiply the heater full amp loads by 150 percent and subtract the resulting number from 125. The end number will be the MOCP for a unit with field-installed electric heat.

## Tip

- If you do not know whether your electrical unit is a single-point power unit or a unit with field-installed electric heat, consult the instructions manual or call the manufacturer.
