Moving a consumer unit - a couple of questions
Our house consumer unit is currently on a stud wall in the downstairs
loo, we are planning to extend the loo into the adjacent utility room to make a shower room. Thus the consumer unit needs to move, it can't be in a shower room and the wall it's mounted on is going anyway. I replaced the original consumer unit with the one that now needs moving so I'm not too worried about the basics of what's needed but I do have a couple of questions:- Some (quite a few) wires will need extending, I have suitable crimps and crimp tool but what protection do the resulting joints need? All the existing cabling is T&E laying between joists etc. but presumably crimped joints would need forther protection. Is heatshrink enough or do they need to go in boxes of some sort or conduit? I *guess* this may be Part P'able, I'm not too concerned if it is or not to be quite honest but it would be nice to know as there will be building inspectors around for other work that is going on. I'll be buying a new 18th edition all RCBO consumer unit, any recommendations for good, easy to wire ones? -- Chris Green · |
Moving a consumer unit - a couple of questions
The consumer all rcbo unit I have is a curve M18 unit from denmans electrical.
It's replacement will be an all metal enclosure as mine was fitted before the consumer unit regulation amendments came into force. |

I'm not absolutely sure yet, I'm hoping I can move it somewhere that won't need the incomer to be extended. They come underground across the drive and, I assume, up a service duct that also holds a downpipe. I'll need to have a look inside the boxing in to see what's what. BTW it is part P notifiable but who cares? Yes, my feelings exactly, I'll just have to keep the building inspector's eyes averted. -- Chris Green · |

One of the issues that came up on the survey was the consumer unit being in a shower room. Not just a room with a shower but a full wet room. Luckily for him, he actually wants to change it into his "home office". (It is the only bath or shower in the house but it is on the ground floor. Very odd idea.) So he won't have to do anything about moving it. |

Yup consumer unit change would be notifiable. I'll be buying a new 18th edition all RCBO consumer unit, any recommendations for good, easy to wire ones? Hager are usually ok - not too pricey and good range of modules available. However it might just be a case what's got the best special offer on it. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Part P mentions new circuits or changing the unit as notifiable, but exempts extending circuits - although that was probably never intended to apply to the consumer unit end. SteveW |
