Wiring Problems

[afswift]

Hi,

I have recently completed some electrical work at home, which involved moving (about 10m with suitable 80A isolator) and renewing the consumer unit. This is all complete, passed all tests and i labc have checked the work.

I have a few problems,

1 The installation seams to be using alot more power, the bills are higher than before, only really added mains smoke detectors and a small amount of outside lighting, but i have split some circuits up that were just on the socket circuit i.e. alarm system, home office radial, garage ring etc

2 Also maybe linked to the above problem but when i plug in a kettle or vac the lights flicker very slightly.

Alyone have any ideas on what the cause could be?

Cheers,

Adam

Thats what is confusing,

every circuit got excellent readings for loop impedance and insulation, polarity is also correct on every outlet.

So dont understand what could be wrong, not come accross this before other than in older houses with a very small outdated incoming supply.

Have you double checked the tightness of the neutral connections in the CU and the isolator?

What about the R1+R2 readings?

Are all the connections nice and tight, including into any external isolators, henley blocks, main switches, busbars, neutral rails, MCBs, accesories, junction boxes etc?

Does anything including the meter, cutout, CU etc get warm while the flickering takes plase?

Can you hear any crackling noises anywhere in the house?
