Extending a ring...Outside

[phb]

I went to look at a job today where the client requires power for an office being built in the garden

The consumer unit is under the stairs in the center of the terraced house. Putting in a new circuit would mean having to pull up the bottom steps of the wooden staircase, pulling out part of a parquet floor and surface mounting along the conservatory to get outside. a hell of a lot of work and making good would need to be done afterwards

there is however an outside socket on the wall of the conservatory that is part of the downstairs ring

I had thought of extending the ring from there... I have tested the circuit and calculated what the additional impedance would be and it is well within parameters

what's peoples opinion on doing it this way and has anyone else done such a thing?

It's not a great idea but if it's the only way then...

What did the customer think to ripping half the flooring up?

do you not think it needs it's own feed to prevent nuisance tripping?

 

[davesparks]

have you considered going up the outside of the house, under the floor upstairs and then down the back of the staircase?

I did that once Dave when I locked myself out, never again I got covered in cob webs:lipsrsealed2:

You know all this nuisance tripping everyone keeps speaking of, ask yourself this, how often does your rcd trip, really? Yeah, never or once a year if your lucky.

See the thing is I wouldnt find it a nuisance,more of an intregue than anything

saves remembering to push test button every 3 months!

i bloody hope not, I still have rewireable fuses.

why mot fit a single RCD then, stop them shared neutrals causing a problem, why not just install one RFC and one lighting circuit in a property too will be cheaper to but a smaller DB.

The two RCDs on my DB have never tripped in the four years they have been installed.....probably seized up!! That's on wiring ranging between 30-70 years old at a guess, including a four ft run of lead sheathed...

I do like the idea of all RCBO boards, but on domestic they are generally overkill.

What load do they think they need???

Seen a house like that once.

in Kidderminster.

two rewireables, power and lights
