Drill a 1" (2.5 cm) minimum diameter hole in the right rear or left rear corner of the support surface for access to the junction box. NOTE: For under counter installation, the junction box should be located in the adjacent right or left cabinet.Calculate the minimum box size: NEC ® 314.16 (A) and (B) describes the detailed way of counting wires, as well as clamps, fittings or devices (i.e., switches, receptacles, combination devices) – by establishing an equivalent conductor value for each.By accurately sizing your junction box, you ensure compliance with safety standards, prevent potential electrical issues, and optimize space usage. The calculator takes into account several factors, such as the type of conduit, conductor size, and the number of conductors.
The NEC 2023 includes specific provisions for sizing junction boxes. These requirements ensure that boxes are large enough to accommodate conductors, splices, and other components without causing damage or excessive heat buildup.
