usually quit good spared for Mira ( ie new heater elements switches ect ect ) might work out cheaper than a full unit.

don't want to be a sourpuss but do check your mains elect for your shower is up to 10.5 .
I had to rewire to bigger rated cable when I upgraded my shower, something I almost overlooked.

CRAIGR - 20/10/10 at 05:07 PM

Good point.
Tis a pretty thick cable going to a 30amp rcd i believe. Current shower is an 8.5. Anyone know if thats ok??

Armchair opinion....The 8.5 will (I think) be on the edge of what the RCD (and hence probably cabling) will handle...so would not recommend going any higher

(8500kW/240v = 35A)

CRAIGR - 20/10/10 at 05:19 PM

Just checked it and i lied its a 40amp rcd.

is it a 6.0mm2 cable?
if so it wont carry 10.5 kw. you will ned to put in a 10mm2 cable. hope this helps

CRAIGR - 20/10/10 at 05:28 PM

Outer casing of cable is at least 10mm Dan

If you haven't a clue what you are doing don't risk it, you'll probably burn the house down.

HOW DO I KNOW WHAT CABLE SIZE I HAVE?

1mm² CSA T&E has overall dimensions of 7.8mm x 4.25mm

1.5mm² CSA T&E has overall dimensions of 8.2mm x 5mm

2.5mm² CSA T&E has overall dimensions of 10.3mm x 6mm

4mm² CSA T&E has overall dimensions of 11.9mm x 6.25mm

6mm² CSA T&E has overall dimensions of 13.5mm x 7mm

10mm² CSAT&E has overall dimensions of 17.1mm x 10mm

16mm² CSA T&E has overall dimensions of 19.4mm x 10mm

Outer casing of the PVC insulation has nothing at all to do with the current carrying capability, of the 'cable' !
The important cable dimension is the;
(cross-sectional area of the copper conductor) in mm(squared); csa
of the copper.current carrying conductor !

slingshot2000 - 20/10/10 at 09:35 PM

Peteff,
I agree with you about the sizes you have quoted, for British Standard sized cable 'outer sheaths@ , the should be good!
BUT, can YOU guarantee the the cable that may be used to supply a 10.5kw shower is adequate, if you dont know who made the cable ? Or where it was made?
I have seen many samples of unregulated cable being used in very dangerous conditions! Make sure the cable 'YOU' spec for 'your' job , is capable of carrying the current required by you application !

Be careful out there, dont suggest something you wouldnt do in your own home !

I have found a whole kitchen hanging off a 2.5 twin and earth and a shower hanging off a long run of 4mm.......

Did you read the first line of my post? I'm not going to guarantee anything over the internet just pointing out that the " Outer casing of cable is at least 10mm Dan " is no indication of what it is wired with. Now where's that get off your high horse smiley.

Now now chaps we've gone slightly off topic and for peace of mind an electrician has been called.
Many thanks for all the advice as always though guys .
