    Hello,

    I have a question regarding the safety of my shower.

    The other day, the power to the shower went off as I was just finishing using it.
    Then the trip switch for it at the box refused to stay in the on position.
    I informed my landlord and he said he would take a look, I hoped he would get an electrician, but he decided to have a go at fixing it himself, he took the cover off the shower and off the panel where it is wired in and had a look around..... in the end he said it might be a faulty trip switch at the box, I was then gone out for the day and when I came back later, I think he has replaced the trip switch with one that says 140a , after doing some internet research, I am only finding things saying that a shower should have around a 40a fuse.
    So, is it safe to use my shower? as 140a is a huge difference from a 40a switch.

    Please see attached photo.

    That's just the part number, look at the next line, hidden in your photo, it will say B40, which is a 40 Amp, 'B type' MCB.

    It's still a bodge though, using a different brand and leaving that gap down the right hand side is unacceptable.

    You're right, it does say B40, thanks for the reply, was a bit concerned. Yeah well you know how some landlords are, it's not the only thing in this apartment that's a bodge.:rolleyes: Thanks

    It's a 40A as above - but it's the wrong make for that board.

    What is the rating of the shower - such as 8.5kW, 9.5kW, 10.8Kw ?
    Is this installation located in Ireland?

    It's a Mira Go, not sure what kw rating as it's not labeled anywhere on it. Yes, located in Ireland.

    Rules on who can do electrical work are entirely different in Ireland. Your landlord should not be doing the electrical work himself.

    The rating of the shower is important, because it may use more than 40A, and could be overloading / damaging the circuit breaker.

    Whereabouts is this installation?

    An MCB is not permitted for an electric shower - it must be supplied by a dedicated RCD (i.e. an RCCB serving only one MCB or, more usually, an RCBO).

    Also C20 MCBs should not have been used - the socket-outlets are required to be on B curve MCBs.

    As above with @flameport RE: Restricted Electrical Works.

    You must by law get a Registered Electrical Contractor (REC) - i.e. RECI (aka Safe Electric) member involved - if this installation is within the 26-Counties. If he interfered with electrics in a Special Location then he has committed a criminal offence punishable by up to a €15,000 fine and/or 3 years imprisonment.
