Identify the type of branch circuits through the following d

Identify the type of branch circuits through the following different system schematics. ________ ________ _______ Based on the name plate of a motor shown below, please point out the (1) rated full load ampere, (2) service factor, (3) design code and its meaning. A small retail store is being constructed. Its power supply is single-phase. 120/240-volt. The store is 80\' times 60\' and has several loads: 25-kVA air-conditioning unit 5 ampers, 240-volt ventilating unit 60 duplex receptacles 40 linear feet of show-window lighting 1.2-kVA outdoor sign lighting Copper THW conductors are used as feeders. What size should the current carrying feeders be?

Solution

*Individual branch circuit that supplies a single load.

*Multioutlet branch circuit that supplies to multiple loads

*General purpose branch circuit that supplies multiple outlets for appliances and lighting.

*Appliance branch circuit that supplies a single appliance load.

*Multiwire branch circuit is the circuit with two or more ungrounded conductors and one grounded conductor

1a). General purpose branch circuit because circuit has different load (A, LTG, and one more)

1b). Multioutlet branch circuit because circuit has multiple load (load is Appliance A)

1c). Individual branch circuit because circuit has single load.
