Also, if its a wylex cartridge fuse board, and not rewireable, then the plug in MCB's will not fit.
maybe it's a regional thing but I've never come across a cartridge fuse board round hereAlso, if its a wylex cartridge fuse board, and not rewireable, then the plug in MCB's will not fit.
Can you post a picture?To clarify, I don't have an RCD but the main 'on/off' switch incorporates an "earth leakage circuit breaker".
I believe this has a similar function to an RCD but is not sufficient for new installations. (It has a 'trip' button to test the system).

It doesn't make any difference to the thread but the 8500 will likely be at 240V so a bit lower amperage.
Even less at 230V.
[well, it is Saturday night ] .... even the resistance of the element won't be completely constant. The element will be presumably be cooler (hence lower resistance) with less current flowing through it - so, if it's resistance is 6.8Ω with 240V applied, it will presumably be less than 6.8Ω with 230V applied, hence the current will be somewhat more than 33.9A (but less that 35.4A).Nope. The resistance of the element is the only constant.
8500W @ 240V = 6.8Ω - 35.4A
7800W @ 230V = 6.8Ω - 33.9A

True, but you'd have to change the water flow rate to get the same temperature (hence same element resistance) if you changed the applied voltage.Yes, but it will be constant at a temperature.
I don't know - you tell me!! As I said, it's Saturday night! Do I take it that you are a teetotaller?OMG!!! talk about perdantic! are you related to my wife?!, If resistance is proportional to 'kelvin, then the difference would be ~2'k = 1/150th, why am I even replying to this!!!
