Building your electrical system with the industry’s best

Panel boards, distribution boards, circuit protection devices, and disconnect switches are essential components in any electrical power distribution system. Greenville Electrical is proud to offer these imperative devices from leading manufacturers, including Dorman Smith and Schneider, helping you implement a system that is guaranteed to deliver.


We hold an extensive stock of components needed to facilitate the distribution of electricity in addition to disconnectors, fuses and circuit breakers, available as MCBs (Miniature Circuit Breakers), MCCBs (Moulded Case Circuit Breakers) and RCBOs (Residual Current Circuit Breakers with Overcurrent Protection), to protect your people in the event of a system fault.
