About this service
A junction box is a specific type of enclosure used to safely join two or more wires together. It acts as a protected meeting point that keeps connections secure and accessible for future maintenance. You typically need one installed if you are extending a circuit or adding new lighting where wires need to be spliced safely. Building codes strictly require that all electrical connections remain inside an approved, accessible box to prevent sparks and potential fire hazards.
