You asked: How do you protect electrical tools?

To protect the user, electrical tools must have 1) a three-wire cord with a ground and be plugged into a grounded receptacle, OR 2) be double-insulated, OR 3) be powered by a low voltage isolation transformer.

What is used to protect the electrical equipment?

Fuses and breakers are also used to protect electrical appliances and equipment from damage or complete burn out due to overload. The fuse or breaker at the breaker box is sized to protect the wire, but is not necessarily sensitive enough to protect a small-use device plugged in on the circuit.

What is the main protection in electrical hazard?

Fuses and circuit breakers are designed to protect conductors and equipment. They prevent wires and other components from overheating and open the circuit when there is a risk of a ground fault. Ground-fault circuit interrupters, or GFCIs, are used in wet locations, construction sites, and other high-risk areas.
