Question

The main types of overcurrent protection used for a condensing unit are:

1) Circuit Breakers
2) Fuses
3) Overload Relays
4) All of the above

Answer 1

Circuit breakers, fuses, and overload relays are the main types of overcurrent protection used for a condensing unit.

Step-by-step explanation:

The main types of overcurrent protection used for a condensing unit are:

1. Circuit Breakers: Circuit breakers interrupt excessive currents to prevent thermal hazards. They are rated for a maximum current and can be reset.
2. Fuses: Fuses protect a circuit from currents that are too high. They consist of a short piece of wire that heats up and breaks at the rated current.
3. Overload Relays: Overload relays are another type of overcurrent protection device. They are used to protect motors from excessive current.

All of these options can be used as overcurrent protection for a condensing unit.
