Hi all
Went to a job the other day where they wanted an additional electric shower, they've currently got a PME system with the following usage :
electric cooker 32 amp
shower 32 amp
lights 6
lights 6
---split board---
boiler 6
sockets 32
sockets 32
And they want to add another 9.5kw shower to that.
Checking the board and supply and found they had 100 amp main cut out - 16mm tails to meter - 16mm tails to 60 amp fuse and then 10mm twin and earth to the board.
I've recommended the 10mm t&e and 60 amp fuse be removed and replaced with 25mm tails and 16mm earth, I believe I'm justified to say that due to the high potential usage of the house, I understand the 10mm twin was protected by the 60amp fuse as its current carrying capacity at clipped direct is 64amp however if another shower is being added and much younger tenants will be using the property there is a potential the two showers, cooker and some sockets would be in use.
what do you think ? What would you do ?
Thanks for your time !
