spare fuseboard

[Mephisto]

Hi all. I will do some ring, lighting, smoke alarms on the new loft for my client. I haven't space in the old fuseboard, so I thought to install a second small fuseboard. Should I connect earthing cable to the pipe? Thanks for any help.

Are you bonding cable tray as it's an exposed conductive part and it can become live under fault conditions? In this case the fault would have to be a damaged cable I'm presuming?

Yes. It is quite conceivable for a cable to get damaged on the edge of tray and make contact.

Ive watched a video on the eFixx YouTube about this before and his opinion was that if the cable could introduce a fault which made the cable tray live, this would suggest the cable or containment is unfit for purpose.

Cant see the logic in this personally as surely that would mean only SWA could be installed on tray so the armouring became live rather than the tray if there was a fault?
