[QUOTE="Apache, post: 20275, member: 828"] Is the SWA to the sign or a rubber flex? Are you saying SWA leaves building and rubber flex arrives and this is the mysterious joint you are searching for? If you put a rod in and there's only a L & N then you'd be safe AND there's no risk of earth leakage back to this rod as not connected to main supply. What sort of sign is it? If double insulated does it actually need an earth? [/QUOTE]
