Garage & other external buildings

[cliffed]

Finished a Eicr,just your thoughts on this,the remote garage is supplied from the ring main of the house,other building are radials of this.
The supply enters from underground,& are pvc t&e,goes straight into a 2g power point,then to other points.
There is no main bonding required,thinking this needs isolation when entering the building,& other supplies protected accordingly.
Would you fit a small DB on the main in,or a complete no no,cause it’s a ring main.

No such thing as an equipotential bonding zone anymore.

This is a death trap either disconnect the supply to the garage or board it up to prevent use it is outwith the equipote ncial zone

From what the OP has said why is the supply to the garage a death trap? It's part of the ring circuit of the house. Yes it could have been done a lot better. The OP needs to find out what is protecting the two T&E cables going to the garage.

Sorry @cliffed I missed the size of the radials in your post. You state that they are going to 'other buildings' but what for? Could you put a FCU in so the 2.5mm will be ok? What is protecting the 2.5 radial cables? How are they routed to the other buildings?

Yea we can put spurs in to protect the other circuits.
Thanks for your guidance,I agree it could of been done better,the ring to the garage comes from the rcbo supplying the ring main to the house.
My concern was really an isolation point,looking & reading all replies ,I’m thinking of putting a switch spur on the incoming ring,then feeding the garage,then the remaining supplies off fcu’s.
The other radialsare serving power & lights in a couple of sheds.Isolation at those points will be 20 amp Dp.
The bug bear to me is the supply,& knowing the best way to actually comply to regs correctly.
Thanks

Will the customer be happy being limited to 13A for the garage and the 'other buildings'?
What are you going to do if the T&E cables that go to the garage are just buried in the ground without any protection? You need to know what is going on here before you can fix things.

 

[cliffed]

Agree,but how do you know how they are installed without digging the patio up.
13 amps will have to do.

But what you are suggesting is to alter the circuit to the garage and the 'other buildings' when the cables to the garage may not comply with regs.
You are doing the changes and your name will be on the cert.
If the cables going to the garage are to regs then all is fine. If not then this will need sorting as well.

oh no, he's going to be gender whatever.

What else can you do,it’s not ideal at the moment,but it will be safer than before,noted on cert,there’s no way you can actually say yes or no to the cabling already installed.

You can make a good guess by exposing a few feet of the cable run at each end, to see if the cable has been butchered in or done properly, but don't be too dissapointed at what you find.

Sorry,it’s remedial works,the client wants it to comply to latest regs.

As what @Pete999 says. Not wanting to sound harsh but without knowing if the cables comply you are not doing what you quoted above. Just do it properly mate.
You don't want someone down the line doing an EICR on the property and them coming on here saying "someone was meant to update this work but the cables to the garage and other buildings don't comply. What a muppet..."

 

[cliffed]

Kinda agree but,there are limitations to what can be done,it will be noted on the cert.
There is no agreement that the cables will be re-cabled.

 

[Octopus]

There is no agreement that the cables will be re-cabled.

What does the EICR code and what have you been asked to quote for?

Too many variables IMHO

 

[cliffed]

A report was given,my company listed the remedials,we are completing the list,C2 was the original code,this was for the ring main into the garage,& what we could do to improve the situation on that.

But if the cables going into the garage don't comply then your suggested changes would still make it a C2, wouldn't it?

 

[westward10]

What does the original C2 actually state.
