Lights Dim When Appliances Kick On

When this happens, the cause is too many electrical devices drawing power from one circuit. If plugging some devices into receptacles on other circuits doesn’t solve the problem, you may have to upgrade your home’s electrical service panel.

For today’s electrical needs, a main electrical panel should deliver 100 amps of power or more; 150- or 200-amp services are even better for homes fitted with generous lighting and electrical amenities.

A main panel sized smaller than 100 amps may be overloaded, which can cause lights to dim when appliances kick on and may lead to frequent home power outages. If this is the case in your home, talk with an electrical contractor about installing a new, larger electrical service panel.
