Ring to radial

[Plonker 3]

So you have the option of reinstating the RFC or just disconnecting both ends of one leg.

Why not reinstate what is there leaving no cables loose in the back of a socket or DB. What happens when they decide to start plugging more appliances in, as believe me customers dont always tell the truth about what they have plugged in.

Surely if it's just stated happening there could be a fairly easy to pinpoint problem?

charge them again for changing it back to a ring ;-) haha

One other thing OP have you done your cable calcs for volt drop and worked out if the Zs value will be compliant?

Pah.... making a right meal of it. Would you really sit there doing cable calcs for this?? I wouldn't. He can go at least 2.40 Zs on B16 60898. Experience would tell you, fit MCB and derate to radial, Quick Zs, MW, Done.

You've saved me asking.

But for a Electrical Trainee what does that matter, he’s got the cash in his pocket and ridden off in to the sunset.

Well yes I would and I am pretty sure most others on here would do too.

Anyone that doesnt design every circuit they install is in my wyes just a chancer that thinks of nothing but lining their own pockets.

 

[TJ Anderson]

You've saved me asking. He’ll be bloody lucky if it’s compliant.

He'd be bloody unlucky if it wasn't compliant!! Lighting Zs on 1mm 6242 in a house is very rarely over 1.50 Zs, this is 2.5mm. Real world.

Charging unnecessary time is lining your pockets. Using your experience to save a customer money is not.

 

[Anthony S]

what do you think?

AdieB

I would cover myself and go for a full rewire

 

[Plonker 3]

Then what happens if the Zs and volt drop are not compliant?

Who pays then?

Something wrong with your eyes :54illb?

 

[telectrix]

wye eye, as geordie would say

On a serious note though, you make a valid point, but chances are if VD and Zs are ok on the old ring, they'll be ok on a lower rated radial.

This is not an excuse not to check though.

Though. Just thought I'd throw in another though as two didn't seem samey enough, Lol.

And another lol in case Eng 54 is reading! lol.

Even if Zs was a bit over for MCB, which it almost certainly won't be, I would have no problem in utilising the 30ma RCD to provide satisfactory earth fault disconnection in this instance. This is not designing new circuits, this is getting someone up and running when they have a problem.

Here you go Voltz, I thought you might like to use this for your Avatar.

Pure laziness. Besides what happens if the RCD fails?

Replace the faulty leg get it back to how it was before and get paid.

oh my god. Exactly what I was going to say. Absolutely ridiculous. Some on here just look for holes and use that to flex their BYB muscles.

Crap. You are obviously out of practice.
