10 Bedroom house rewire. Ring or radial?

[Moaz]

Is that actually coming into force? Radial per room? That’s a joke. Unnecessarily filling up the DB..

As far as I've understood. It's true, unless someone can correct me.

same here.

Maybe I misunderstood. I'll check it tonight.

Where will you be checking tonight? Where did you see it originally?

Originally another spark mentioned it. And a few weeks later, I heard someone else mention it too. I've not checked the draft myself, but I need to now.

This is what I have as info.

not true.

But we will have to take into account earth leakage when designing circuits.

Not sure how to do this!

Tell you 'em you spoke to me, and I said it ain't true.

See how easy it is to make these things up

 

[Pete999]

Is it a HMO dwelling?

This is what I have as info.

Yes I have that as well no mention regarding the OPs post as far as I can see

 

[elsparko]

How?

the best way to learn not to stay up all night is to have to wake up early and feel like ----

Yeh right calculate earth leakage! Also longevity of cable and who will be using it throughout it's life and how many times per day subject turning on and turning off, no problemo!

 

[Octopus]

Yeh right calculate earth leakage!

Its unbelievable but due to be in the 18th

Be interesting to hear how the IET and scams think installation designs comply or don't comply.

Would have been far better if they had simply stated

"RCBO's for socket circuits"

Anyway Moaz wire it how you like. You know the property and it's layout.

Just be aware of you cable lengths and do your calcs...and you may need to do 4mm radials if the property is that big..

R1+Rn (which you can get from Onsite guide)multipled by the rating of fuse you want to use multipled by the correction factor of 1.2 (70c)

Simple job done.

HMO?? I'm thinking her majesties something?

not if there are seperate CU's on each floor, depends how big the "floor" is though, it might be 10 small box rooms or david camerons house

 

[Marvo]

Surely if the implementation of arc protective devices is imminent this would be another reason to use radial circuits...??

Your right it could be very small but the OP is the one who's been there
I think Moaz said it was large, he didn't say if the DB on each floor was at the middle or the end of the house. So who knows how long the radial could end up being.

and how can they be tested?

HMO?? I'm thinking her majesties something?

House of multiple occupancy

i.e. where a property is let out "by room" and the landlord lives else where .................

a very big hot potato ATM

 

[Marvo]

Student digs type places?

Why a hot potatoe?

 

[elsparko]

too many variables to assess from offsite basically

more like an old folks home, their own rooms sometimes their own toilet, shared kitchen and living area
