Hello electrical mafia, Just a quick one for you on this fine evening…..been asked to do the electrics for a hot tub install, house is a TT system and has no upfront RCD the ZE reading is 12 ohms. Would I be ok to split tails in a henley block and feed hot tub from a garage unit that has a 30ma RCD main switch or does an upfront 100ma need to be fitted to whole install swell as this. I haven't had much experience of TT systems and thought I would ask the finest bunch of sparks about for there wisdom.Thanks
