Re: Bad work practices still rife in trade
But isn’t checking EFLI with a tester checking the effectiveness of the earth connection? So, if it wasn’t there e.g. at consumer unit, the EFLI test would give a fail result. 😕
I can see that bonding to metal neighbouring to appliance being worked on also should be checked, especially with elderly appliances or those which give a less than wonderful insulation result.
I think you have to draw the line somewhere. It’s not our job to take responsibility for the whole house electrical system, though if we find an anomaly we should point it out and give appropriate advice on who to call.

No. It is not saying the same thing twice. You could get a satisfactory EFLI reading via gas & water pipes (especially if they are metallic) and other strange parellel paths. Carrying out EFLI tests with no main earth & or bonding could introduce unforeseen shock hazards.
This is why it is important to verify prescence of earthing and bonding.
Agreed, if you find no Main Protective Bonding and/or no main earth, proceed with caution & advise the customer to seek assistance.
Keep in mind that main protective bonding is somewhat different to the Main Earth even though they are all inter-connected at one point.
The point being made is, that if you are carrying out EFLI measurements, understand what you are trying to achieve and measure, and do it safely.
If you would like me to expand on any of this, I would be pleased to do so.

That would be excellent. I for one, would be grateful for that. Perhaps you could just do it gradually so as not to overburden us with too much info at once. Take your time please, and simplify, simplify to the best of your ability.I’m particularly a little concerned that, if I understand correctly, even when going into a house to fit a new door handle to a washer, I am expected to ask the customer to show me the consumer unit. And if I don’t find it there, where should I look?
