4mm flex it is then.

Yes - I get your point, but the techical data in their booklet says "Fuse protection 32A" ... and two lines down ... "2.5mm 3 core" - these aren't even compatibale with each other??? EFLI - I'd like your thoughts on how I should proceed here (and any others thoughts please?) Currently I...

I thought it was 27A max with no correction factor. In addition the circuit goes : CU -> 32A breaker -> Cooker switch -> CCU (Hob) -> CCU (Oven) Lamona says 2.5mm for the hob and 1.5mm for the oven. I reckon the Hob need 4mm and the Oven needs 2.5mm, as with a 32A breaker and CCC of...

Instruction for lamona 6.5kW Hob states 2.5mm 3 core - isn't that too small/just on the limit? Protective device is 32A?

Replacing a kitchen fan - and got one that has L, S/L, N connection. It is fed by the existing T&E. I thought that putting the L to the S/L connection would enable it to be operated as a simple fan with no run-on, but it doesn't. Instead I have to simulate a L, S/L feed by making a...

Hi Bigall - E7 Storage Heaters is the main source - OK may need to go higher wattage, but I'm not even at first base because I don't know requirements outside 0.6m for IP rating.

Thanks for the links - I'll take a look. It seems to me that 512.2 is just a complete cop out, after being very specific regarding zones in a bathroom, the general 512.2 clause doesn't really help - It ends up being very subjective with one spark saying "what if someone took the shower head...

Can anyone help me on this - The regulations refer to Zone, 0, 1 & 2. I cannot see any requirement outside zone 2 for a particular rating for a heater? All circuits are RCD protected. Is there a particular rating required for a heater? I sense there must be a requirement in a bathroom but...

Thank you - yes it has no window and just about fits a sink, toilet and bath. I see that 60cm is outside the zones hence my thought about putting it on one of the walls, so does that mean it requires no IP rating at all? Seems a bit odd in a bathroom?

Looking for a cheap small panel heater for bathroom about 400W. If I put it on one wall it will be 60cm away from the bath, if I put it on the other, it will be within 60cm of bath. What IP rating considerations are there and does anyone have any recommendations of a suitable product.

Nice one - one of these before the tundish should do it then? http://www.norscreenfilters.co.uk/warning_pipe_kit.html Everyone agree that THAT would then meet the regs?

1. OK - are you saying it's the insect thing that's a problem? 2. It appears from the regs that if you fit an audio alarm, it obviates the need for a warning pipe (and therefore by implication the regulation that any warning pipe must exclude insects). So fitting a tundish with an high...

.. and what about when the water tank is in a cupboard - can you fit a tundish there?

So the water regulations say that you can fit a tunish in a kitchen but not a loft because you have to use a loft ladder to see it. A link would be useful, as I thought the precise purpose of a tundish was to meet the water regulations in that you can see the water is overflowing, regard less...

I thought that you can see the water in a tundish? http://www.advancedwater.co.uk/images/unvented-guide/figure12.jpg

Ok - so that keeps the terminals far enough apart so that a droplet of water doesn't register a fault - and it is close enough so that when the trap fills so it can register the fault - it will definitely short at that distance? I spoke with glow worm and they said that the normal cause is...

We have a boiler that exhibited this error. Condensate pipe is indoors, so no freezing pipe issue - Glowworm suggested taking off the earth lead - boiler worked. They told us to dry the connection after removing it at the condensate pipe and so when replaced worked (there was a droplet of...

I was referring to the impedance of the MCB and RCD as the only difference between the measured Zs and the calculated one - I've looked at a number of other forums, and it appears as someone earlier said that No Trip Zs readings can be spurious and unreliable, so I am assuming this is the...

I suppose we are adding in RCD's and MCB's into the equation when doing the Zs?

Yup - with the probes at the socket, and as the radial is pre-wired conduit, L, N and E are all 2.5mm, and I am getting exactly 0.18 ohms for L-N, L-E and N-L. Yes, socket plug in Megger, tested four different sockets, each roughly the same.
