Junction boxes are intended only for wire splicing and branching, while distribution boxes are designed for circuit protection and power distribution. The National Electrical Code (NEC), published as NFPA 70, sets minimum safety standards for electrical junction boxes in residential and commercial buildings. It measures 6 ½ inches x 4 ¼ inches x 3 inches and contains six relays and twenty-one fuses connected to a base.

Home distribution boxes typically handle single-phase power supplies and contain 6 to 24 circuits. They include standard circuit breakers for lighting, outlets, and major appliances like water heaters and air conditioning units. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. What is a Distribution Board? A distribution board or distribution panel (DP) is an important part of an electricity supply system.
