Thanks IQ. But what if user is wearing wellies and there's no RCD protection in garage (but is in house). User is holding failed tool and therefore a live part, hasn't got a shock because there's no earth path but then touches water pipe on side of garage. Will MCB or RCD in the consumer unit in the house provide any protection? If no, then shouldn't earthing be improved in the garage (e.g. bonding of this pipe and either TT or 10mm2 back to consumer unit). Thanks, SW.
