Ring main too big??

[Boaky]

I recently tested a doctors surgery and found a number of ring mains
are too large. r1 1.9 rn 1.9 r2 2.7. Zs 1.47 supplied from a type 2 32 amp breaker
could anyone suggest how best to rectify this.
Dont really want involved with the remedials but don't usually refuse work.
any of u guys any suggestions

Did you check all accessories for a decent connection?

Im sure 1 ring main should not cover more than 100m2 floor area

 

[daniel hill]

Yes as jay Sean, maximum size of a ring is 100m2

Sorry to point it out again but there's a hell of a difference between 100 metres square and 100 square metres.
Obviously the regs state the former but there does seem to be a lot of confusion over the matter

Fit a 20A breaker?

 

[bri38]

did the test involve visual inspection maybe wire came loose when putting the socket face back on

Fit a 20A breaker?

Not sure if a 20 amp would hold in
i tested at the board aswell and got same reading

 

[trev]

Why would a 20 not hold? What's the loading on the circuit?

 

[Boaky]

A few computers, printers, a small kitchen
think your right a 20a is the cheapest and easiest way to rectify

I think you'll need a slightly more scientific calculation to convince a doctor of your "remedy"!

What is the floor area of this place? I can't imagine it being a massive place. As someone said above, did you check all terminations to make sure they're nipped up nice n tight?

 

[Boaky]

It's an old building over 4 floors
basement, ground, 1st, 2nd
havent done the floor area I was just trying to pick some peoples brains
really

 

[trev]

So this one RFC serves all 4 floors?

Not if it's my doctor who just nods and smiles at everything I tell him - which is why six months down the line I am still no nearer to finding out what is wrong with me than I was at the start!!!
