Correct best but in certain circumstances the immersion can be taken off the ring main and doesn't need its own circuit

I went to service a megaflo about a month ago and had Main and boost immersion wired together using a single cable into a 16amp circuit breaker.. disconnected the boost immediately!!!Correct best but in certain circumstances the immersion can be taken off the ring main and doesn't need its own circuit
I knew you would add that!

Sparks use 13 amp fused spurs on everything and leave the 13 amp fuse in them on heating wiring etc.
Idiots! Never trust a Spark.
On the subject of 13amp spur switch on immersion’s being totally wrong, - my house had same in airing cupboard as the final isolator for immersion. Had been working perfectly for over 40 years of daily use, until I replaced it with a 20 amp switch with neon.
But the old MK switch was probably better quality than the new switches
2 x 3kw elementsBoth 3kw immersion or a 1.5kw and 3kw ?
2 x 3kw elements
Lol I were’nt gonna Flick the switchdid it blow the fuse ?
Lol I were’nt gonna Flick the switch
Funnily enough the cylinder was heated by the boiler so I didn’t need to test them both.. just disconnected the boost and tested the main.Chicken was it warm ?
Probably shouldn’t say this but I do my own wiring.Most can't even wire an s plan it's getting less and less that are able to do it
Probably shouldn’t say this but I do my own wiring.
Same here..Probably shouldn’t say this but I do my own wiring.
And do you realise standard 13amp fcu will be rated at around 18amps for safety (able to take 13amps easy)
Yes, a friend of mine is an electrical/electronics guy and told me the fuses are rated much higher.
Not sure what extra % of amps he told me, but think he said they could take surges for short periods.
I am still trying to learn the more technical bits of electrics.
Twas I, many moons ago !I actually had the same point about immersion switches on this forum and it was clarified by some of the more electrical experienced guys, maybe Shaun.
The immersion works on the limit of 13amp, so a spur switch that is 13amp might burn out at the internal switches (for neutral and live) or at the 13 amp fuse.
It depends on if the supply is 240 volt or if it is lower, because the amps raise if voltage lowers I think.
Normally you will have 15 or 16 amp fuse or the mcb fuses at electric consumer unit and then any switches on that for the immersion should be 20 amp 2 pole switches.
As Shaun and Best have already said, If the Volts drop the Amps rise.Cheers last!! An electrician wired up the immersion lol immersion’s don’t draw more than 13 amps, why would you need a 20 amp switch?
Twas I, many moons ago !
Apologies Mr Last!
Without trying to find the thread, I do think I recall it was indeed you who had informed me about it being wrong for 13amp spurs to a 3kw immersion.
Why are you not a Trusted Advisor on here yet, come to think of it?
I’ve got one and I’m useless most of the time I’m sure it will not be long before they realise you are goodI must not be worthy! lol
I must not be worthy! lol
Hey Jay,
Tidy looking install, you’ve done really well to cram all that lot together in there.
Not looking for faults, but on my phone it looks like you have tee’d in the blow-off from the heating system at expansion vessel with the expansion relief blow-off at the inlet group?
Didn’t know regs had changed to allow combining of potable and heating system discharge?
Hey Mikeygas, I have yes. I wasn’t aware of any regs that disallowed this..Hey Jay,

Don’t think there is mate. It is allowed in all the instructions I have seen.Hey Mikeygas, I have yes. I wasn’t aware of any regs that disallowed this..
