Hi
New to this part of the forum so go easy on me. Got a job which need some views on. It's a factory unit with smaller businesses running off the same incoming supply with separate private meters. Now one part is still running of the private un metered part so they want me to run a sub main install and 3 phase meter and 3 phase board. All ok so far. Now it's 3 phase as they have 2, 3 phase sockets (currently connected on old supply) which feed these industrial handheld car spray jets (its a car cleaning company).
[FONT=Arial, Verdana, Helvetica, sans-serif]The rest is single phase so plan to install a RCBO for the 13A sockets however the 3 phase one are a concern. Currently only supported by a 3 phase MCB. Now I don't recall but think they are either 20 or 32 Amp but are dedicated to this specific item so don't think they need RCD protection however although the actual plugs are inside Im still wary of the water ect. Problem is what's the best way to protect these and do I need to? Now as 3 phase RCBO's don't
exist I could put a 30MA RCD incomer as it's only going to be a 4/6 way dis board. Any thoughts Am I going over the top??[/FONT]
