Spur for diswasher and washing machine in radial circuit

[yarcyk]

Washing machine and dishwasher if on at the same time and heating water can be around 4-5kW as both have similar heating elements.

Nothing at all wrong with a radial. aslong as you install 4mm2 cable protected by a 32amp in the kitchen. 20amp with 2.5mm2 cable serving the bedrooms and another 20amp radial for downstairs.

Easier to 1st fix(no return to c-unit).Easier and quicker to test.Easier to fault find.Less cables in fuse box to 2nd fix. I think its the way forward. Some sparks cant see past the "ring final circuit".

Obviously i do still install rings but im leaning loads more to a radial circuit. My NAPIT assesor put me on to the idea "why u still messing around with rings" i quote.

Only for electricians that are ignorant of the benefits and adaptability of Final ring circuits. You design a circuit of any description based on the needs and requirements of the situation, taking possible future needs/requirements into consideration....

"beem me up"

 

[seb77]

at the end of the day it can still only take 32amps pal

I seem to remember that you could only do this within 50sq/m, where a ring could be in 100sq/m, so correct me if i'm wrong, i'm getting old and forget things real quick.

The only thing on for any length of time is the washing machine, and that's only using 2kw when its heating.

Buy a hot fill machine, use gas to heat the water!

I think it would be a ---- up whether it would be cheaper to use water heated by gas or electric nowadays.

I believe the uk is one of the only countries to use a ring circuit. The reason been is when you cut through the cable you have two radials running off the wrong mcb. You might not beable to cover such a large area using radials but at least you dont have a problem spuring off.

 

[Rockingit]

I tend to use radials where appropriate for 'house' circuits, and RFC's for kitchens, utilities etc.

I just can't see why (in a properly designed circuit) a flat screen telly needs to be provided with 5mm2 of copper. But a kitchen, that's a different matter.

Floor area/csa/rating considerations taken into account, there's no more flexibility in a ring than a radial, it's just an economic argument on loading as to whether it's cheaper/more eco friendly to run the whole circuit in 4mm or just need to run a return leg (let's face it, not normally that long) in 2.5mm.

i agree england is the only country to use a ring circuit invented because of the war. there is already talk of doing away with the ring curcuit so that once again we can fall in line with our european bretherin

As far as I'm aware, the OP's intention is to spur off of a Radial , not a RFC.
As for there being talk about doing away with RFCs, there has been talk about such ever since they were introduced.
The IET has no intention of doing away with RFCs, and considering the current high price of copper, it is more likely that other countries will be introducing RFCs themselves

Ooo. If there's one thing that winds me up.

Me too, don't people know that it should be a capital E?

 

[trev]

I thought it was spelt Engerland now

 

[dingledong]

20 years ago maybe all in capitals but now were nothing special
