Fused spur from an immersion switch?

[Darkwood]

To re-iterate though the suggestion the OP made wouldn't fall foul of this but a similar suggestion KAS1 suggested with a machine and microwave oven most likely would as a fault with the microwave could interupt the supply to the machine and cause major disruption to production and downtime costs.

Recommend dedicated

If i wire 1 light in the cellar of the dist board it would be called dedicated because its on its own not because its required to be dedicated, if i then want to add say a fan through the wall off the same circuit does that mean im not allowed because it holds the title dedicated or as i suspect can i just put on the CU cellar light and fan and no longer give it its sole title. I.E. Demote the nature of the circuit.

That's my point, let's not encourage people to bend the regs for the sake of a bit of laminate flooring, just give to the customer straight it can't be done without a bit of a bodge up. You have to be hard with them and when you catch them taking short cuts sack them, look how many on here think it's perfectly good practice but they don't seem to like the idea of running outside lights from the Immersion heater what's the difference lol

nobody has suggested it's 'good practice'....The OP's original question concerned regulations,not good practice. Dont lose sight of that.

Sometimes I wish I could sack the customer!

At last you see sense, that's why he asked the question about the regs so he knew it wasn't the done thing so to speak, giving them the advice people have they'll do it every time if it's "a bit hard to do it" then they pass that on to someone else and then on it goes.

Most jobs would be 100% better if they didn't have customers!

Your misunderstanding my comment the reg 314.1 really has no scope in domestic as inconvenience is already minimal at most and rarely would create a hazard to be affected , lamps blow mcb's sometimes this is an inconvenience and following that reg' to the word and not giving common sense ground would mean filiment lamps couldn't be used but the inconvenience is more about disruption, downtime of computers, machines etc effecting numerous people or even losses in earnings and idol staff if a machine goes down due to unrelated fault..

Experience and judgement call is necessary here and using this reg out of its context is overkill, apply 314.1(i & ii) only where a hazard or true inconvenience is caused not where at worse the customer may have to switch off the immersion heater or respectively the wall heater to isolate a fault and allow the mcb to reset with re' to the OP case.

look after this I'm done here....but I'm not going to let you twist words to your own ends.
'Good Practice' generally means that it is the first and best way of doing things...you have suggested that contributors to this thread have implied that when wiring a heater it is 'perfectly good practice' to wire it from the immersion heater....that is NOT the case.
It can be done safely and within the regs, but it would not be the first choice method and nobody has said it is.

It is something a DIY'r would do :devil: don't you think ? wind up :57: honest !

Is this really still going on? Haven't read but are the handbags away yet?

 

[Geoffsd]

One final point ???

Which other 'dedicated' circuit do we design so that Ib is half Iz?

It would suggest some spare capacity, don't you think?

i carry a knuckle-duster in my handbag.

So it might be, but why encourage someone who doesn't really know what he's doing, to commit bad practice, this is the a sort of question if someone on site asked me I would think Oh my God where has he learned his trade and send he back to the agency lol

KAS, I do hope your not suggesting that all agency sparks are incompetant.

 

[KAS1]

No, sorry my apologies that was not called for, I should never of posted that, once again my apologies,sorry if I upset anyone I wasn't thinking, that was a stupid thing to post up on the net, I can assure you it won't happen again.
