What is a Panel

Find information on the "panel" from Master Electrical Service.  The electricians from Master Electrical Service offer explanations of the panel also known as the breaker box, electrical box, breaker board, etc.

The panel has several different aliases:  breaker box, electric box, electric board, breaker board, service box...All of which describe the same thing.  We refer to it as the "panel".

Your panel, depending on when your home was built, can be in a variety of different places.  In newer homes it's probably in your garage or outside, in older homes it may be in a closet or room.  No matter where it is, we recommend that you keep the area easily accessible, with no less than 3ft of clearance around it.  You should know where your panel is, and know how to operate it in case of an emergency.

The panel controls the electricity coming from the utility company into your home.  More specifically, the breakers that are attached to each circuit regulate the amount of electricity or AMPS.  If a problem arises like an overloaded circuit, the breaker will trip,  this preventing any electricity flowing into that circuit.  Once the issue is resolved, the breaker may be turned back on the enable electricity to flow throughout the circuit again.

The panel is the heart of any electrical system.  A good panel can prevent serious damage and protect against hazards.  If you are unsure about the state of your panel, Give us a call today and we will be more than happy to discuss it with you.

  • It is older than 15 years - if unsure of age of panel, what is the age of your home?

  • Several different brands of breakers are installed - look for different colors or manufacturer labels
