TL;DR
A load center is the residential breaker panel that receives the service conductors and distributes power to branch circuits through a main breaker and rows of plug-on breakers. Units are rated by bus amperage — 100, 150, or 200 amps in most homes — and by the number of spaces, with modern panels offering 30 to 42.
What it means
A load center is the residential breaker panel that receives the service conductors and distributes power to branch circuits through a main breaker and rows of plug-on breakers. Units are rated by bus amperage — 100, 150, or 200 amps in most homes — and by the number of spaces, with modern panels offering 30 to 42. Electricians evaluate its remaining spaces and bus rating before adding loads like EV chargers, heat pumps, or kitchen circuits.
