Metal back panel of distribution box
North American distribution boards are generally housed in enclosures, with the 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. carry the current from incoming line (hot) conductors to the breakers.

At is the distribution box
A distribution box, or DB box, is a circuit breaker enclosure. It is a vital part and central hub of any electrical system. The hub distributes electrical power from a single input source to various circuits throughout a building. It integrates power distribution, protection, and monitoring capabilities, and is responsible for distributing power to entire commercial or residential. A distribution box, often simply called a DB, is a crucial component in any electrical installation.
