**Adjusted Sub-Total
NOTE: **If four or more appliances are installed on a leg, adjust the sub-total
of that leg by multiplying by 60% diversity factor.
NOTES:
* Omit smaller of these two, except include any motor common to both functions
** If system consists of three or more independent units adjust the total by multiplying
by the 75% diversity factor

Calculated total amperes (load)
NOTES:
1. Add amperes for free standing range as distinguished from separate oven and cooking
units. Derive by dividing watts from Table III by the supply voltage, e.g., 120 volts or 240 volts.
2. If the total for Legs A and B are unequal, use the larger value to determine
the total power required
