Ping ARW!

I promised a follow up to the EICR performed on my rental house last
Friday.

4 C3 advisories.


1. Position of earth rod for garage not found C3

As mentioned before, a 10mm earth wire comes out through teh wall and
disappears into the gravel. Removing said gravel woould then reveal the
top of the earth rod and the earth rod connection.Â* I shall fit an
eartth rod inpection box to resolve this one

2. No grommets on cable entries on garage sub-consumer unit.Â*Â*Â* C3


The Sparky clear was not concerned that there was no RCD or MCB or RCBO
in teh garage CU, its just a simple on off switch followed by 2 ceramic
catridge fuses.

In his defence, he did follow back the SWA to a 13A fused neon switch in
the lounge which in turn is connected to a 32A RCD & MCB protected ring
main.


3. 6 circuits have no RCD protection C3

These 6 a

Hob
Double oven
Lights up
lights down
Smoke alarm/emergency lights/intruder alarm
Outside lights.

(There are 3 further circuits that are protected by a single RCD, which is

kitchen sockets
Boiler
Whole house sockets (its a 2 bed semi)

4.Â* No RCD protection in bathroom C3

This one puzzles me a little as all there is in the bathoom is a ceiling
light, a wall unit light and an extractor fan on the upstairs lighting
circuit and is one of the 6 circuits mentioned in No 3.....


I happen to have some spare ways in the CU so I am actually tempted to
rip out all the MCBs and the RCD and put in 9 RCBOs.

Howeever, is it an issue if the RCBOs are NOT teh same make as the CU
casing

or would I be better off replacing the whole CU with a fire retardant
case and with matching make RCBO's?

Thanks for getting back.

I am amazed that the plastic CU was not noted as C3. I would have noted it.

I knew the earth rod and cables in plaster less than 50mm would be C3.

As for the bathroom if there is supplementary bonding (usually to rads,
sink bath etc back to the light fitting) then it is a C3 (not to current
regs but met the regs when installed). If there is no bonding it's a C2.

Please do not put a different make of RCBO in your CU. What make is it
that you cannot get RCBOs for (or you can but they are £100 each).



My advice would be that (as you are already prepared to pay for 9 RCBOs)
then you might as well swap the CU for a metal one and leave enough
space in it for a SPD if it becomes a reg in a few years time. Or even
fit a SPD with this CU change. I believe that SPDs will be mandatory in
a few years time on all CUs.

Finally - I always make a note if the smoke alarms are past their
replace by date. There is no reg that says I can class that but it's
always good for good landlords to know that they need replacing.
