At my parent's house I'm labelling up the consumer units (1 main and 1 extension). I have an annotated JPEG at link: https://u.pcloud.link/publink/show?code=XZV4rEkZEqbx7HxCrRpPWwxEPSGpKXsrA4QV Am sure that the labels in the link are below: 1, 2 - 100A main consumer unit switch 3 - B16 RCBO (protects MCB labels 4,5,6) 4 - B6 MCB 5 - B6 MCB 6 - B6 MCB 7 - RCD (protects MCB labels 8,9,10,11) 8 - B32 MCB 9 - B40 MCB 10 - B32 MCB 11 - B32 MCB 12 - RCD (protects MCB labels 13,14,15) 13 - B6 MCB 14 - B32 MCB 15 - B40 MCB Can I please have help in confirming that the labels above are the correct consumer unit labels? Thanks
Coloumb: I believe labels 1,2 are together a 2 pole main switch. A clearer photo is at link: https://u.pcloud.link/publink/show?code=XZiMrEkZWbooACHxRHfzG8re295IByOJJK3y. You agree?
Colmec: If 3 is a B16 MCB which label is the RCD/RCBO which protects labels 4,5,6? Please can you let me know, thanks
You don't have an RCD protecting 4.5.6 it is a main switch you have a 16th edition consumer unit with one RCD
What you have is potentially dangerous You have a GE board with CGD (control gear direct) parts and Proteus parts- some of the parts don't line up properly Reg 536.4.203 states (in simple terms) that consumer units should only have parts inside designed / approved by the manufacturer. I would recommend a board change and an inspection / test .
Also looks like a loose piece of tape next to the main switch rather than a proper blanking plate. Not going to do much to prevent a finger poking in and potentially coming into contact with any exposed live parts.
Would the MCB's need switching to just GE approved MCBs? Also yes I should get blank MCBs for the sections covered by the loose tape. Would you recommend, if the main consumer unit board is going to be changed, changing the MCBs for RCBOs?
Unlikely in its current state. Also likely if that’s the state of the CU an inspection is going to uncover further issues with the existing installation. What we could do with is a front on photo of the whole CU(s). Choice of RCBO vs alternatives is down to a competent designer of electrical installations. Your particular installation beyond the CU and equipment you wish to connect could have an effect on the design.
Main consumer unit photo: https://u.pcloud.link/publink/show?code=XZHuVOkZm4R219gKmr5iHrY3WMQkKHNrTpj7 Extension consumer unit photo: https://u.pcloud.link/publink/show?code=XZjuVOkZPWawjfanqK4bflXMe0mAlRiAsXM7 The outlet cables from the various MCBs on the main consumer unit are surface clipped to the wall but are not mechanically protected.
If you mean the Consumer Unit would result in an unsatisfactory EICR (Electrical Installation Condition Report) then maybe. Having MCBs/RCBOs from different manufactures would normally be noted as a Code 3 unless there was evidence of heating or other damage preventing the correct operation and IP rating of the CU. If this was the case then you could expect a Code 2 and an unsatisfactory report. One way to ensure a Code 2 is get a company in to do the EICR that relies on remedials to make money.
No, mcbs 1,2,3,4 are not RCD protected mcbs 6,7,8,9 are RCD protected depending what circuits are on 1,2,3,4 it hard to say what code an EICR would give, although the tape on the DB is a code 2, my advice would be RCBOs or change the DB
