Total 3800W This loading is not OK
.
It exceeds 3500W.
Notes: 1. Each receptacle of the duplex can provide 15A/1800W. Do not parallel the two 120V duplex receptacles.
2. Do not parallel the two 120V circuits.
3. Do not parallel the two duplex outlets.
Calculating total power provided by generator.
(See Section 11 − Generator Power Guidelines)
Each receptacle can provide the watts or amps as shown
above. However, the total power can not exceed 3500W.
The rating plate on electrical apparatus will contain the watts
consumed or the rated input amps. Watts may be calculated by
multiplying the rated voltage by the rated input amps.
watts = volts x amps
