How do you determine disconnect switch size?

A properly sized disconnect switch for a single motor will:

  1. Have an ampere rating greater than or equal to 115 percent of the rated motor full load current; or,
  2. Have a HP rating greater than or equal to the rated motor HP (at applied voltage) if the disconnect switch under consideration is HP rated.


Is a disconnect a switch or a breaker?

A fused disconnect switch is a combination of a switch to disconnect the circuit and a fuse to shut the circuit off in the event of a problem. When installing or maintaining equipment on the circuit, or the circuit itself, the switch provides a method to manually shut off the power.

What size breaker do I need for AC disconnect?





Most homeowners usually need help with determining the breaker size for 220/240V breakers. For smaller 1-ton (or up to and including 15,000 BTU) AC units, you only need a standard 110/120V circuit with the standard 15 amp breaker.

How many receptacles can be on a 20 amp circuit?

The answer to the question how many outlets on a 20 amp circuit is ten outlets. Always comply with the 80% circuit and breaker load rule, allowing a maximum load of 1.5 amps per receptacle. Remember that your circuit, wire sizes, and outlets must be compatible to avoid overheating and electrical hazards.

When should you use a disconnect switch?

In industrial applications disconnect switches may be used to interrupt power to machinery and motors when there is a safety hazard or when repair is needed. In fact, disconnect switches are mandated by the National Electrical Code (NEC) to be used in all industrial and manufacturing facilities.

How do you install a disconnect switch?


Quote from Youtube video: Step one will be to turn off power. And then um locking and tagging that power out because we don't want anyone to turn the breaker on while we're working on it.

What is the purpose of disconnect switch?
