Right, before anyone says anything i am not going to attempt this myself, i will get an expert in. However i would like to know how it's done so i can't be fobbed off / conned etc.
I've semi installed an electric shower, everything apart from the connection to the consumer unit. The problem is, it is not possible to buy MCB's for this old fashioned unit (typical), so i've got a dedicated shower consumer unit complete with MCB/RCD. How is the spark going to connect this up? my current supply set up is as follows:
The supply comes into the house via a 60A tamper proof fuse, then through the meter to the existing consumer unit (Rated at 100A max), although it could never draw more than 60A else the main fuse would blow i guess? The existing Unit has the following MCB's fitted, 40A (cooker), 30A(downstairs ring), 30A (upstairs ring), 15A(immersion heater) and 5A(lighting), Is that no overloaded already? all those MCB's add up to 120A max which is 20 more than the C/U rating and double the main fuse. So this is why i am confused?
Will the sparky have work with the live wires as i see no way of turning the supply off apart from at the cunsumer unit.
Me confused again
