Extent of Electrical Installation Covered by this Report.

I went to this job today. I have re-read the original E.I.C.R. One thing that stood out today was the old cutout main fuse. The carrier is clearly marked 60 Amp. It was sealed but not fully home. I can't explain that. The fuse inside was indeed a 60 Amp fuse. The E.I.C.R. states it as being an 80 Amp fuse. Why?

Because the original Inspector made it up.

Probably as he didnt want to remove the fuse, and be liable for a fine from the DNO.

He should have put ‘LIM’ in the box.

Or the fuse had been changed since the EICR was compiled…

Or simple human error… (mis-read hand written site notes when back at the office)

I believe that the 60 Amp fuse was the original from Noah's time. Very old and original. Complying with a 1953 B.S. printed on it. The seal was wire with a circular lead seal.

I can't imagine anyone putting an 80 Amp fuse into a 60 Amp carrier where the carrier is clearly marked by the manufacturer as being rated at 60 Amps.

Another point of interest. The old consumer unit was a Crabtree make. It had a 100mA main switch and M.C.B.s. It is very good quality, but a first for me. The surround/mounting frame was wooden. I have seen wooden framed Wylex boards but not wooden framed Crabtree boards.

An 80 A fuse might not even fit, depending upon the type.

Update. The building surveyor's electrician charges £145.00 per consumer unit, and takes about 2 hours according to the nice lady at the office today. Presumably this is for the limited “consumer unit only” type E.I.C.R.

Was a paper seal from the Supplier applied after you had determined this ?.

The extent box is rather more than that Andy. If the installation is much larger then it is used to show from what DB onwards is being reported. In a bigger install, say a hospital which has a number of buildings, then it is perfectly reasonable to inspect one of them, or perhaps just a part after an incident, say a fire. It is not to look at a single item! This is a deliberate abuse of the EICR system, as one was advised from the "old" 2391.

I was asked to do an EICR for a customer a few weeks ago on the extension wiring only as the original installer had not provided any certification 6 or 7 years ago. This had been suggested by the council so that he could get it signed off.  This comprised of 3 circuits from an existing DB.  The extent box is useful sometimes.

Yes Gary, just as you say, but not just the CU, it says virtually nothing useful!
