I'm not sure if the Regs allowed separately bare earths.

I've been on this job to do an inspection before fitting a new RCD OR RCBO board. In most of my career until now the CPC is inside the T+E cable. This property has a separate CPC all through out the building. Only where there has been modifications, modern wiring has been used. If I can prove the ZS is good, is it ok to connect to this system. It's seems to be mainly the lighting that is wired in single sheathed cable which has been ran in conduit. I am hoping if anyone has any information regarding the regs about separate bare earth running through the property. There is a risk of borrowed neutrals if changing to an rcd or rcbo board. The customer does not want a Rewire but wants spots fitted and sockets moving. I have convinced him to change the board, now I am worried about nuisance tripping. However if you could advice about the earth mainly would be a great help. Personally I feel the wiring was good for it's day.

What type you got them breakers at.

Some of the cables have been moved to another breaker as they have just gone, in the on position the output has no life.

These are old federal Electric breakers they don’t trip for anything you can have a short and it will blow itself clear before it ever trips what are you talking about coding the earth situation?

Yes please

Because some are saying that it is a potential hazard, so I'm wondering if they have a compliance code for it.

Yes please

On an EICR I’d code it a C2. And explain to the customer why a rewire is definitely a good idea.

An installer from BT found that out a few years ago when he drilled a ring cable, the only thing to stop the arcing was when the conductors burned back into the melted PVC. The MCB didn't trip. The staff said the bang was tremendous and scared the isht out of the bloke.

The contacts often remain closed on these when they have been switched off which is something to watch out for. Truly terrible devices.

They did a stab-lok version too they were famous for arcing, overheating and causing the back end of the breaker to melt into the busbar and basically weld the breaker below into the busbar

Sham, if you change the boards, I would be interested in these for the museum. They are Federal, rebadged by ECC (Electric Construction Co.) back in the day that UK switchgear makers were cloning or importing US gear. We have a lot of ECC plant but none of their boards. They were one of the four main UK makers of mercury arc rectifiers.

After reading all this, should i not change the board If the customer does not want a rewire. And write in my cert why. Departures.

Have you done an EICR and the customer is now asking for remedials.

I used to have quite an impressive stock of both these and Dorman smith stuff and bits of the boards. I never even thought that anyone would be interested in them and chucked them 2 years ago when we moved house. I would have gladly given them away for free.

YES, but not rewire.

And alterations

Personally I wouldn’t be installing anything new without at best a full rewire or at worst a new board and bonding upgrade but that’s your call how you play it
