I would welcome your thoughts on this.
I am installing a defib unit for the charity I do work for. it's not a complicated job, just a spur off a RFC, via an unswitched fcu. Basically, the MI says this cabinet(which includes a heater and fan) must be installed on a circuit with RCD protection and have a 13A fuse. There is an option just to put a plug on it, with a 13A fuse, but I am electing to go via an unswitched fcu, and the circuit has rcbo on it. My question is about the cable protection. It is H05RN, so a rubber cable sheath, 3 core, but looking at it I see maybe 0.75 or 1mm at best. I'll check tomorrow, but even at 1mm I think the ccc is maybe 10A max, at 0.75 it is maybe 6A, and it will be installed in conduit. My query is whether a 13A fuse is appropriate. Please let me have your comments on this. As most of you will know, I am not a qualified electrician, but I just feel this is almost "bell-wire" and a 13A fuse won't blow at 13A, more like 20A after a while.
Thank you in advance for your assistance.
