A safety switch (also known as a “disconnect switch,” or “load break switch”) serves multiple purposes, but its primary functions are to function as a disconnect means for a service entrance and a disconnect means and fault protection for motors (heavy machinery).
Is a disconnect the same as a breaker?
Circuit breakers and disconnect switches are equally capable of preventing the return of power, once they are opened and properly locked and tagged. The real difference is that a circuit breaker can trip open when it detects an overcurrent situation.

This applies to your HVAC unit, your attic exhaust fans, and other major household equipment. In addition, the NEC states that this disconnecting means must be a device included on their list.
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.

When should a disconnect be fused?
The goal of a fused disconnect is to open a circuit and disengage power quickly and definitively in the case of an overload or short. When potentially harmful electrical problems arise the fused disconnect detects them, the fuse blows, and the equipment is shut off automatically.
What is an electrical disconnect?
Electrical disconnects are switches that isolate all wiring in a home or other building from the source of power, typically the utility power service. Also called the service disconnect, this is the first disconnect device after the utility meter.
What is the name of the panel that feeds the electrical disconnect?
The electrical disconnect may feed the main service panel (breaker panel) in the home. The feeder wires connect to the main breaker in the panel, and the neutral wire connects to the neutral bus.
What is the line side of a breaker?
Feeding the Line Side of the Breaker. The two hot wires connect to the top two lugs of the breaker , called the "line" side of the breaker. The neutral wire connects to the silver-colored lug along the side of the breaker. This wire typically is marked with white phasing tape to signify that it is the neutral wire.
How many volts does a disconnect switch receive?
Disconnects receive 240 volts and lethal current from feeder lines coming from the utility meter. The feeders and the terminals they connect to on the disconnect switch are live at all times unless the utility has shut off the power to your service. The disconnect switch does not shut off the power in the feeders lines or at the switch connections. Disconnect switches must be installed by a licensed electrician.
What is a breaker rated for?
The breaker is rated for maximum current, measured in amps. For example, a home with 200-amp service will have a disconnect breaker rated for 200 amps. This is standard for new home construction. Older homes may have 150-amp, 100-amp or lower service capacity.
Where is the neutral wire on a breaker?
Two "hot" feeder wires connect to the bottom of the breaker. A neutral feed wire connects to the silver-colored lug along the side of the breaker. This wire is marked with white phasing tape to signify that it is the neutral wire. There will also be a ground wire leaving the disconnect.
Can you disconnect a service panel on the outside of a home?
It's also possible for a home to have a service disconnect on the outside of the home, while the main service panel — with its own main breaker — is inside the home. Each of these configurations involves specific wiring techniques and requirements that are not interchangeable.
