Excellent points as always!But if the enclosure was bought as an empty enclosure would the same rules still apply, and for din rail enclosures designed to take circuit breakers and the like, what range of equipment is approved by the manufacturers to fit in their enclosures?
Ok, can you advise what tools should be used please?
I always remember testing Zs at a block for students, new build our company did, using a kewtech kt64 my colleague recorded 0.00 ohms, block was about 30 meters away and the cable was 120mm2 4 core swa with separate 70mm cpc.No, and I never suggested you should not use the tools you currently have.
I am just pointing out that we all need to be aware of the accuracy and tolerance of the test equipment we use.
loop impedance tests can have quite a high tolerance at low values.

What was the measured PFC?I always remember testing Zs at a block for students, new build our company did, using a kewtech kt64 my colleague recorded 0.00 ohms, block was about 30 meters away and the cable was 120mm2 4 core swa with separate 70mm cpc.
My megger 1552 recorded 0.05 ohms (zs)and at the main distribution panel a ZE of 0.01 ohms which tallied up with the DNO design figure.
So I do realise the tolerance levels of different manufacturers testing equipment.
Just an example of 2 mft meters with different outcomes at low values.
Again it’s as accurate as I could get with the equipment used.
Where at the origin or the block?What was the measured PFC?
Don't think it actually says that you can't mix devices, there are procedures to follow if you do need to mix and match.Right, regs is regs so I will not mix and match CU components.
The reasoning being from thepocket lining barstewardsmanufacturers is we haven't tested so we wont take responsibility for the installation being safe.
My question is, if you arrive at a CU with preexisting mixed components can you carry out works on it?
The procedures are that the designer/installer becomes the manufacturer and has all the obligations that apply to a manufacturer.Don't think it actually says that you can't mix devices, there are procedures to follow if you do need to mix and match.

An even less likely scenario that the your average spark having a CE accredited testing facility in his garage.think what pete means is that if you get confirmation from,say, wylex, that hager MCBs can be mixed in a wylex board, you're good to go.
If you were to ask Hagar whether their MCBs could be used in a Wylex board, the answer would very likely be yes.think what pete means is that if you get confirmation from,say, wylex, that hager MCBs can be mixed in a wylex board, you're good to go.
I don't think it would. Although the wholesaler would gladly sell them to you for it.If you were to ask Hagar whether their MCBs could be used in a Wylex board, the answer would very likely be yes.
Have asked this question of a manufacturer in the past.I don't think it would. Although the wholesaler would gladly sell them to you for it.
