Distribution boxes are not a type of equipment

Distribution boxes are generally not considered electrical equipment themselves; they are enclosures that house protective devices and facilitate power distribution.Function of Distribution BoxesA distribution box, also known as a DB box or sub-distribution box, serves as a central point for distributing electrical power from a main supply to multiple downstream circuits. Its primary role is to divide incoming power into smaller circuits and house protective devices such as circuit breakers, fuses, and residual current devices (RCDs), which safeguard both people and connected equipment (E-abel, NUOMAK) . Distribution boxes ensure safe and efficient power allocation but do not actively perform work themselves—they support the operation of electrical equipment rather than being equipment in the functional sense.Classification and ContextDistribution boxes differ from control boxes or active electrical equipment. While control boxes contain components like relays, contactors, and PLCs to control, regulate, or automate machinery, distribution boxes primarily route and protect electrical power without controlling the operation of devices (E-abel) . Similarly, junction boxes are used for cable connections and branching but do not constitute equipment either. Distribution boxes can be primary, secondary, or tertiary, depending on their position in the power distribution hierarchy. Primary boxes handle main incoming power, secondary boxes serve specific areas or floors, and tertiary boxes connect to individual appliances. In all cases, the box itself is a passive enclosure, while the devices inside (circuit breakers, RCDs) are considered protective equipment (AS Beam) .Temporary vs Permanent UseSome distribution boxes, often called power distribution boxes (PDBs), are portable and used for temporary setups at construction sites, outdoor events, or emergency power situations. Even in these cases, the box is a housing for outlets and protective devices, not active equipment, although it enables the operation of connected tools and machinery (Lianjer, LED Controls) .ConclusionIn summary, distribution boxes are not considered electrical equipment themselves. They are enclosures that provide safe and organized distribution of electrical power and house protective devices. The actual equipment is the machinery, appliances, or devices connected to the circuits protected and distributed by the box. Their classification as enclosures rather than active equipment is consistent across residential, commercial, and industrial applications.

North American distribution boards are generally housed in sheet metal enclosures, with the circuit breakers positioned in two columns operable from the front. Some panelboards are provided with a door covering the breaker switch handles, but all are constructed with a dead front; that is to say the front of the enclosure (whether it has a door or not) prevents the operator of the circuit breakers from contacting live electrical parts within. Busbars carry the current from incoming line (hot) conductors to the breakers
