Loose Connection
A loose connection is a common electrical problem where wires or components aren't properly secured, which can cause various electrical issues in homes and buildings. Think of it like a loose handshake - the connection is there, but it's not firm enough to be reliable. When electricians mention this term, they're referring to wires that may have become loose at outlets, switches, circuit breakers, or junction boxes. This is important because loose connections can cause flickering lights, intermittent power, create fire hazards, or damage electrical devices. It's one of the most basic yet critical issues that electrical professionals deal with regularly.
