Main Electrical Panel

From rLab Wiki

The Main Electrical panel is where power comes into rLab, and we use a lot of power! The wiring is being updated at the moment so this page was accurate as of 19th September 2018 but should NOT be considered authoritative as regards the current wiring setup, please check very carefully what the actual situation is before carrying out any electrical work.


The main incoming feed is bottom left on the panel, which goes through the power company fuses and meter and into the large master isolator switch on the left. This interrupts all power in the entire hackspace when used. The maser isolator feeds the 3-phase distribution board, the single-phase distribution board and the 63A 3-phase special purpose socket. The 3-phase distribution board then goes on to feed special-circuits 3-phase board which powers the lathe and the 3 x 3-phase power points in the space. DB-3A is a contactor board that was intended to operate the lathe and laser cutter but is currently un-used.
