Hello forum world This is my first post but I've gleamed a lot of info from here in the past.
My sister rang me up to say her electric shower wasn't working. It appeared to have power, but wouldn't switch on. I knocked off the entire power to the house as the fuse box isn't marked as what's what, and found out it was the water pressure sensor.
Anyhow, after I'd figured that out and ordered the new part, it struck me that there are only three 30A breakers in the fuse box (old Wylex thing with old style fuses). Without pulling them, that sounds like hob/oven, upstairs sockets and downstairs sockets. There is not a larger fuse in the box, and as the shower is rated at 9.5-10.34kW, surely using I=P/V, that's 41.3 - 44.96A.
Without opening the box, it sounds like it's been wired directly to the commons and as such has zero protection. Would that be a reasonable assumption? I haven't got round to fitting the replacement part so it still doesn't work, so it's safe for now.
Any help appreciated.
Cheers
