To size the feeder, please compute the receptacle load for a department stoic having 165 duplex receptacles. How many receptacles can be place on a 120 volt, 15 amp circuit?

Solution

ANSWER

1.for departmental stores the total number of receptacles given are 165. for each outlet the load is 180VA.

for 165 duplex receptacles the receptacle load is given as

Receptacle load = 165* 180VA = 29700VA

Answer

2. The maximum circuit power P= E* I = 120V * 15A = 1800VA

Then divide the power by the load per receptacle (180 volt-amperes) for no. of receptacles

No. of receptacles = Total power(P) / Load per receptacle

                              1800/180 = 10

A 120-volt, 15-amp circuit can supply 10 receptacles.
