Hi,
I've just had an EICR performed on a property that I let. I wasn't
present during the test and my tenant has reported the following back
to me (I'm too impatient to wait for the full report which might not
be with me until the end of next week).

Apparently 4 16Amp MCBs need to be changed to 6Amp. Each MCB is
connected to just one wall-mounted electric heater. The heaters are
rated from 1500W to 2000W.
The last time I had a look at the wiring (when I decorated some 4
years ago), I'm sure it was 2.5mm2 from the MCB to each heater's FCU.
2.5mm2 and 16A MCBs are a good combination, yes? Even 1.5mm2 should be
good.

Surely if I get the 16A breakers swapped to 6A then that won't be
sufficient for a 2kW heater, and probably not even for the 1500W ones?

What possible reason would the electrician suggest swapping to 6A MCBs?
He has a good review rating and was booked via myconstructor web site.
The sparks I've used before is on holiday (whatever one of those is)
which is why I went to that web site.
Ta.

I'm tempted to contact him before he publishes his report as I believe a
copy of a failing report also goes to the Local Authority. It might be
less embarrassing for all if you explain why in some instances 6A MCB
wouldn't be suitable.

Also check if a 10A is available for your CU.

I have sent him a text. It is a bank holiday so won't call him and won't
expect a reply until tomorrow.
I wanted to get some of my facts right before questioning his reasoning
for the MCB change. I now have the wiki to refer to (thanks John Rumm)
so won't sound like a complete idiot!

Yep, I'm sure the report will go to the LA, but eventually if work needs
to be done, or he needs to make a correction, then that will also go to
the LA.

And yes, 10A MCBs are available for this CU at just £3 each.
