# Splice

A splice is a joint where two or more wires are permanently joined so that current can pass from one to the other.

Splices belong inside a [junction box](https://danielelectric.multisites.ai/glossary/junction-box) or other enclosure and are made with a listed connector, such as a [wire nut](https://danielelectric.multisites.ai/glossary/wire-nut). OSHA's rule says conductors shall be spliced or joined with splicing devices identified for the use, or by brazing, welding, or soldering.

Homemade splices outside a box are a hazard. CPSC reports that aluminum-wired connections and splices have been reported to fail and overheat without any prior warning. Because a bad splice can hide in a wall or box, ask a licensed electrician to find and fix one. The [residential electrician](https://danielelectric.multisites.ai/electrician) page lists related service.
