  1. On another thread @Steptoe commented on my electrical setup: I have had a look around and my RCBOs are to BSEN 61009-1, and I think that it is OK if not quite latest best practice. GIven that the setup meets regs circa 2014 I think I am reasonably happy. A few questions if I may: What is a TT system and a TN system? What are the differences and how can I tell which one I have in place? This is my consumer unit. Ferdinand
  2. The manufacturers of our digester has specified an IP66 rated RCD protected socket for the supply for the poo tank bubbler. The dedicated circuit planned for that supply (SWA 2.5, T+E, buried - 10 meters or so) is already RCBO protected. Do I also need RCD protection on the twin socket , or can I simply fit an IP66 socket in the knowledge that the circuit is already protected by the RCBO? I'd like to bury the SWA cable in the same trench that I dig for the poo tank pipe. Bet that's verboten innit?? Thanks in advance @ProDave or @JSHarris or @Onoff or anyone clever enough to know the answer ☺️
  3. I have a studio[flat] and garage run off the house supply. Solar panels on roof of garage, so solar feeds via its control unit into the studio sub-board. Electrician put in MCB to supply/protect mega ducted underground cable to studio sub-board. There is a lot of potential load here with water heater, mini induction hob, ring main, lights, etc. I have been recommended to have RCBOs in the studio/garage circuits to protect and isolate them individually; tho not for the circuit feeding the solar. I am concerned at the lack of discrimination between MCB in house and RCBOs in studio. What is the preferred option for this sort of circuit?
  4. Chatting to the sparky about getting the layout of the circuits sorted and we've decided as previously it will be all RCBO. For an extra £30, is it worth splitting all of the circuits as below..? Bear in mind this is an all electric house which may in the future have solar installed (non-MCS) but only on a south westerly facing roof. Its a 3 bed house, all LED or low energy lighting. Induction hob in the kitchen and electric towel rails in 2 bathrooms along with upstairs electric tile warming (all centrally controlled) and ASHP for DHW and ground floor UFH. Immersion is for boost/legionella cycle.
