3-phase installation Discussion Thread3-phase installation Electrical Advice

Hello,
As part of unlooping the DNO has installed 3-phase residential supply. My supplier has installed a 3 phase meter as well.
I believe I now need to have a 3 phase distribution board installed?

Can any of you guys know how long this would take at all? I do not know what hardware is required?
It would be prudent to install a new CU as well, as the current one is 30 years old.
Thank you for your...

Unbalanced final ring Discussion ThreadUnbalanced final ring Electrical Advice

I have seen a final ring that had the heavy appliances on one leg (L1). Drawing 19.5 amps in total, one leg (L1) was drawing 82% of the 19.5 amps of current. If the ring went up to 32 amps the 2.5mm cable would in theory be just safe enough under the 27 amp maximum.

My question is, if 32 amps worth of appliances were drawing current on L1 would the 82% be reduced as there would be more resistance on L1...

 

Max distance cable can run overhead without support Discussion ThreadMax distance cable can run overhead without support Electrical Advice

Hi folks,

I have been through the regs. Have a garage wired from a house. Cable runs overhead at an appropriate height and is suitable cable. The distance in mid air is about 2m. My question is does this need mechanical support by way of a conduit or tray. It does seem a bit excessive for that distance. Cable does not under tension. Any guidance...

I've just been fettling some 50 year old 2L2.5 pyro (MICC) to relocate a plug socket.

Getting Older and Slower Discussion ThreadGetting Older and Slower Electrical Advice

Hi everyone.
I’m now 50 and find myself taking twice as long doing things that in my head should not be taking as long.
Not sure if it’s an age thing or a state of mind I also find myself double checking things more.
I know I may be comparing to my younger self, who was bought up on a diet of local authority occupied rewires and Bovis new builds, where speed was more of a priority than anything...

Extending wires in consumer unit. Discussion ThreadExtending wires in consumer unit. Electrical Advice

Hi, everyone.

I need to move a circuit to an MCB at the other end of a split load board.

The cables all enter the CU at one end, and the cables in question will not reach the breaker at the other end without extending them. It is a ring final circuit.

What's the best method to do it? I was going to use in line crimps with heat shrink over. Would that be OK?

Any advice...
