I been asked to install new lights into 2 newly formed shower / changing rooms within an existing office floor which is being refurbished. Current set up is lighting busbar in ceiling void, LCMs plugged into busbar which then distribute to light fittings
Question is that the new shower room requires 30mA RCD protection, I've asked the designer to provide details of how to provide this protection but not yet had an answer. Lighting controls company also ignoring the issue.
Is protecting the whole busbar which may have several LCMs and tens of lights hanging off it a good idea, whole floor will have new LED modular lights fitted. Can I simply divert the LCM supply from the busbar through a 13 RCD FCU and make sure that only the fittings for the showerroom come off this LCM. I do realise that there is some issue in BS7671 not recognising RCD FCUs.
Would welcome any ideas or comments.
