Ensure the capacity of the existing power distribution system meets the load requirements for the new installation, including inspection of wiring integrity and confirm the branch circuit voltage matches the voltage of the lighting equipment. The distribution fuse box forms the heart of every electrical system and ensures that lighting systems can be operated safely, efficiently and in accordance with standards. It protects cables and devices from overload, disconnects circuits in the event of a fault and thus guarantees maximum safety. Rated current and voltage: According to actual needs, the. Consequence: the switch in the lighting distribution box (board) is not marked with the circuit name, which brings inconvenience to the use and maintenance. If the switch should not be closed by mistake, it is easy to cause safety accidents.
