Three‑Phase Boards

A three-phase electrical supply consists of a three-wire AC power circuit, an essential element of a commercial or industrial installation which can deliver the consistent and steady flow of power necessary for large electric motors or machinery. A three-phase distribution board will include main current breakers and residual current breakers (RCDs) with over-current protection. It will work to direct the right amount of power to subsidiary circuits to avoid surges and distribute electricity safely around the system.
