Bus Bar Trunking (BBT) is a type of electrical wiring system that is used to distribute power to electrical equipment. It is a more efficient and reliable alternative to using individual wires to connect each piece of equipment.
BBT is made up of a series of metal bars, or trunks, that are connected to each other with metal connectors. The trunks are then run to the equipment that needs power, and the connectors are used to attach the trunks to the equipment.
The advantage of using BBT is that it allows for more efficient power distribution. With individual wires, there is the potential for power loss as the electricity travels from the source to the equipment. With BBT, the power is distributed more evenly, which reduces the amount of power loss.
BBT is also more reliable than individual wires. If a wire breaks, it can cause a power outage.
