A pull box, also called a pull-out terminal box, is an electrical enclosure designed to allow wires to be pulled through conduit systems without splicing inside the box. Unlike junction boxes, pull boxes do not contain permanent wire connections; their primary function is to reduce tension and friction on conductors during installation, especially in long or complex conduit runs with multiple bends . They also provide access points for maintenance, cable re-routing, and future upgrades .
Pull box sizing is governed by NEC Article 314.28, particularly for conductors 4 AWG and larger. The minimum box dimensions depend on the type of pull:
