Electrician Jobs wire new kitchen ring socket & hob & central Heating - Hereford, HR1

[Adryjaan]

Want to make kitchen in new place and need to rewire...
Someone can advice me firstly if thats pics is ok??

To the Central Heating will go 2.5mm
To the hob will be 6mm to double pole switch above worktop then to connection unit under worktop
all other will be on kitchen ring on separately circuit on consumer unit

Some questions:
1) OVEN can be on kitchen ring as showing on pic or should have separately circuit as well? some electrician told me its fine just to plug it into socket other one told me it have to be on own circuit...
2) aplliances like washing machine, fridge, oven supplied with plug, tumble dryer, microwave and dishwasher can be just plug in to ring socket? or should be connected firstly to switch socket? (on my old kitchen all have separately switch socket but i dont know if its option or mandatory...)
3) someone can say me what will be fair price for installing this kitchen?
I want to prepare it for electrician (want make holes and fix plates, make tunnels for cables, drop cables to all sockets) so then electrician can just connect all cables, test it and certificate...

If someone close Hereford can come advice and quote

Regards

1) OVEN can be on kitchen ring as showing on pic or should have separately circuit as well? some electrician told me its fine just to plug it into socket other one told me it have to be on own circuit...best on own circuit
2) aplliances like washing machine, fridge, oven supplied with plug, tumble dryer, microwave and dishwasher can be just plug in to ring socket? or should be connected firstly to switch socket? (on my old kitchen all have separately switch socket but i dont know if its option or mandatory...) FCU or 20A D/P switch above worktop is advisable for easy access isolation but not obligatory.
3) someone can say me what will be fair price for installing this kitchen? impossible to tell without seeing it and determining what accessories you want (plastic/brushed or chrome/etc.

you'll be hard pushed to find an electrician willing for you to do so much of the work. generally, letting you do the chasing and maybe assist installing cables is acceptable to most.

Regarding your oven plugging in.
It's is a recommendation only that any appliance/load 2kw or over is supplied via its own dedicated circuit rather than being plugged into the ring final circuit.
As it's a kitchen with a number of appliances being connected to the ring I would have the oven on it own dedicated circuit as telectrix has pointed out.

i'd also have fridge and freezers/s on separate radial circuit with RCBO to eliminate the risk of defrosting caused by a loss of supply due to a fault on the socket circuit.

Seems like a high load for a ring final circuit.

 

[telectrix]

i'd have 2 circuits for sockets. maybe 4mm radials.

Op why do you require a 2.5mm to the boiler?
Or is it a water heater?

Maybe a good idea to get a competent spark involved NOW and find one is part P registered

It is boiler...
I dont need really as i read its enough 1.5mm it should be fine 1mm too but at the moment in old kitchen is 2.5mm and it is only 3 meters from consumer unit so was thinking about 2.5mm

^^ 1 mm will not comply with the regs

^^ 1 mm will not comply with the regs

Why?
Has a 3 amp fuse in the spur.
Or do you mean manufacturers instructions?

I think its to do with the minimum size for a power circuit being 1.5mm

 

[Ian1981]

I think its to do with the minimum size for a power circuit being 1.5mm

Define power tho.
It's a poor definition in my opinion.
1mm is more than adequate

 

[Des 56]

I completely agree with you Ian
I have considered it as nothing but silliness thats been the motive behind such a stupid regulation
Edit to add
Even a lighting circuit consumes power

 

[telectrix]

think the intention of the regs. was to stipulate a min. of 1.5mm for a socket circuit, but as usual, not made clear and thus ambiguous.

 

[Ian1981]

you won't find any of the motorised valves or the pump wiring in 1.5mm flex that's for sure on these pre wired s plan tanks already made up by the manufacturers as it's untimely not necessary

^^ the circuit to the heating FCU needs to be 1.5mm....... What's down stream of the fcu doesn't have to be 1.5mm

 

[Ian1981]

^^ the circuit to the heating FCU needs to be 1.5mm....... What's down stream of the fcu doesn't have to be 1.5mm

For what reason?
For a circuit which is lucky to pull an amp.

Just going by table 52.3 page 134 BYB ....

Yeah I appreciate that.
Just don't agree, I would say it's a poor use of the word '"power"
Every circuit uses power
