Choose a junction box based on the wiring method, environment, and number of conductors. For indoor, dry locations, plastic boxes are common, while metal boxes are preferred for metal conduit systems or areas requiring mechanical durability . Outdoor or damp locations require weather-rated boxes to prevent moisture intrusion . Ensure the box is large enough to accommodate all wires, splices, and connectors; an undersized box can create safety hazards .
Before installation, de-energize the circuit at the main breaker and verify with a non-contact voltage tester . Essential tools include insulated screwdrivers, wire strippers, pliers, wire nuts, and mounting hardware. Wear insulated gloves and safety glasses to protect against shocks and debris .
