Very old shower replacement

You would need a 40A fuse, for a 8.5kw shower, & a 32A fuse for a 7.5Kw shower.

 

OMG!

Some photo's please.

 

60A

Don't know what the sparks on here think about it, but I think you seriously need to consider replacing that consumer unit to one with mcb's or rcbo's & up to 17th Ed regs, etc.

 

I thought those types of db's were just distant memories,

I would use a shower/garage unit off of Henly to feed shower this would encompass manufacturer/reg stipulations. Cable csa/condition and splicing technique etc all have to be taken into consideration - thus a sparks should be engaged.

 

Oh right -

 

at least that box has a retro fit rcd added so thats a plus.

 

You could most likely get you meter replaced FOC, as was mine here, which was identical to your meter.

 

Does that RCD cover the whole board or just the shower circuit, its only rated at 30 amps. Or does it just do the sockets?

Nothing wrong with the fuse as such, its a 30A HRC and is quite safe, the circuit should be RCD protected either way though. I would be more bothered the size of the cable feeding the shower although it looks like a council re-wire done by Norweb in 1985, it will be either 4mm or 6mm, should be ok for a 7.5kW shower at least.

 

same with the fuses thats how i found out what powered what when i moved into my house as nothing was labeled when i moved in.

 

I'm sure you have to have gas & electric meters replaced by law after so many years.

Done through your supplier.

 

Use to able to slow those meters down with a strong magnet.
