Feed to Shed

Or an electrician who has installed a ring final circuit and wants to fully comply with BS7671.

Please explain. As I said:


"Washing machine, fridge, freezer and oven all come with 13A plugs so no further fused spurs are necessary".

You need to be able to isolate these appliances if their plugs are not accessible.
The only devices allowed to be directly supplied by a ring final circuit must comply with BS1363.

I'm all for having a go at Winston , but -

"Washing machine, fridge, freezer and oven all come with 13A plugs so no further fused spurs are necessary".

You don't really - not regulations-wise.

The only devices allowed to be directly supplied by a ring final circuit must comply with BS1363.

What does that mean?

 

[RF Lighting]

It means exactly what it says.

 

[EFLImpudence]

Well, ok, why did you write it, then? Who has contemplated that?

Or - what have I missed?

Winston, is this all about having two fuses serving each appliance - one in the fused spur, one in the appliance plug?

No problem whatsoever.

It's pointless. With a fault both will most likely go. If you want remote isolation for these appliances use 20 amp switches feeding unswitiched sockets.
But the best isolation for an appliance is to pull the plug.[/QUOTE]

Tricky if the plug is behind the appliance

And it is not compliant with BS7671 to feed a 20A DP isolator directly from a ring final circuit.

And it is not compliant with BS7671 to feed a 20A DP isolator directly from a ring final circuit.

Well it is very commonly done. If it is feeding a 13A socket it can't be overloaded due to the 13A max plug fuse.

 

[EFLImpudence]

Do you really mean from a ring final?

Just because something is commonly done, it doesn't make it compliant with BS7671.

Yes.

From a later thread the general opinion is that it is perfectly OK.

 

[RF Lighting]

Read the regs. It is not ok. Just because a few people say it's ok does not mean you can ignore a regulation.

Let's look at this intelligently.

What is the rating of the switch on a BS1363 switched socket? Is it in excess of 32 amp? If not why not?
