C2 or C3 ? Wrong brand of mcb

[pc1966]

This would be the same BEAMA who are on the list of those behind BPG #4 that has the C3/C2 guidance above?

Mind you, that s not so different from NICEIC who say C2 for no RCD no matter what in thier own EICR guidance, but they also are part of BPG #4 that has the C3/C2 guidance based on risk factors.

manufacturers instructions make no difference to my post earlier.

if you do not adhere to manufaturers instructions , it does not nessisarily mean the installation is potentially or immediately dangerous.

so someone fits an mcb that isn’t the same make as board was designed for, but it fits well, has no impact on other Mcb’s and the buzz bar. Are you saying this scenario is potentially dangerous?
it’s not.

fair enough due to regs and manufacturers instruction# I would not mix breakers, but if it was done prior to my inspection and all was well I would at worst C3 it.

ok the argument is a mcb fitted in a different manufacturer board and some body is stupidly fit one like mr diy or some body is not qualified to the regs , the board catches fire.
you have inspected it and you ok it so ,the insurance company will apply the rules and then what .

But that bodged case is already covered by the BPG#4 guidance.

• No modification of enclosure/assembly = fits without cutting front or bending bus-bar, etc.
• Component is securely fitted and all connections are adequate = above but in more detail
• No signs of thermal damage to component or associated connections = above has not been causing trouble so far.

If it has been butchered to fit, or even if it a little bending of the busbar as its not quite the right location, it is a C2 fail in my mind.

After all, it is possible to fit a matching MCB badly and cause as much if not more fire risk simply buy fscking up the connections! (busbar not clamped as it missed the cage, or terminals loose, or insulation of wire caught by clamp, etc, etc)

I like your argument up to a point,
however I don’t ok it. I C3 it.
improvement recomended.

TBH I have in past not always C3 ‘ed it. In future even if it’s perfect I think I will.

I don’t ok it. I C2 it.
improvement recomended
