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.
A secondary distribution box, also known as a sub-distribution panel, generally supplies power to a specific area. It is designed with inner and outer doors, features a sprayed plastic exterior for safety and appearance, and also has a rainproof top suitable for outdoor work. 💡 Quick Answer: An outdoor electrical junction box is a weatherproof enclosure where electrical wires connect or split, required by code to protect connections from moisture, provide safe access for maintenance, and prevent electrical hazards in exterior applications.
