There ace, and the clips are good too, can get pretty much every type of clip from CEF :)

Discrimination is supposted to take out the plug fuse first, but in reality this doesnt happen! MCB's just too good a match for a plug fuse :D

Well everything here is all installation design stuff which is great fun, if they don't enjoy this I actualy have to agree with you bas, because when it comes to electrical science, I very much doubt they will enjoy that.

No, this is just the begining, what will stop is probably a few more spark jobs because of price increase, this until somthing proper is put into place, I think we might be seeing a few more like this one :? :roll: :roll:

Clearly someone who has no idea of what things cost to do properly, you know the cost of somthing and the value of nothing is what we say.

LOL, Yep SS, must have upset the gods, already had a post removed !

Yep, it's not trying to be unhelpfull, just give the best advice possible to you :roll:

Yep, I believe it was most likely a loose connection, there was complete melting to the terminal block in the shower, think it was only on the incoming phase, also copper completely broken apart because of the temperature rise, and then further back behind the shower on the wall there was...

Well thats what drew my attention to this site, all this talk is a bit worrying yea..

Design calculations aside, whats happened has happened, possibly a loose connection, or possibly a shower fault but that seems unlikely. 6mm I would have to agree should have been fine, but its far too close to play with for 10.5kW, after all Triton reccomend 10mm cable for 8.5kw showers and...

Yes, Supplementary bonding on the bolier, which is cross bonding between all the pipes, this must be unbroken, best way is to remove a section of PVC, say 1 inch or so, then hook this around behind the washer on the earth clamps. hope this helps, seems like you have it well figured out tho...

For the record, PVC like most modern plastics, altho won't sustain fire without melting, if they do catch light they are self extinguisihing, however if you had some Low Smoke and Fume cable it sustains the heat much better, and doesnt let off toxic fumes like PVC cable does.

16mm is fine for your house, you most likely have a 60A or a 80A main fuse, if you needed to have more power, then you would have to speak to the electricity company about having your fuse uprated to 100A, only then would you need 25mm tails.

Yep 4mm Single Copper Earth for the supplementary, no need to bond in the kitchen, Cross bond all the pipes with 4mm at the bolier (this doesnt go back to main earthing terminal)

46A is Clipped Direct BAS... This was tiled over and plastered in the wall, only place it was clipped was for a couple of meters in the cupboard under the stairs. secondly they are my jumping smileys, mine mine mine, you should know better! and lastly........nevermind 8)

You should have a 16mm Single Copper cable for the main earth from supply cable to a Earthing block, more 16mm from there to your board. 10mm Single Copper cable from your earth block to your incoming gas pipe, connection made withing 600mm of the isolating valve, then another 10mm Single...

1311 posts! blimey you should be promoted :lol: cable connected to it was 6mm, backed up by 30A cartridge fuse :roll: hence not good.

Oh and I forgot to add, this is a 10.5kW :roll:

Cheers for pic shaggy, I went around to a house yesterday where there was some trouble with a shower, turns out to be a trinitron jade 3 I think it is, cables totaly melted away right back to wall, the copper is melted too not just PVC, going to need alot of repair work done, and hopefully the...

lol dingbat, I read only from what you wrote, and you decribed how you found the missed earth connection with a loop tester, when you would find this through continuity. no you wouldnt take everything apart, but AFAIC all old wylex boards should be replaced with a more modern board which...
