Hi. Im looking for some advice when calculating submain cables.
Basically there is a new connection of 80Amps that is to be used for a dwelling and a small workshop. I had thought taking to a feeder box with one submain and then two feeds away into the buildings.
A direct run from dno to...
Hi, thanks for the reply.
The run is 100m to a proposed feeder box, then a further 25m to a house and 50m to a small workshop.
What switchgear would be best suited to using a parallel feed? I was goijg to TT this at each connection point with the runs being so long
Hi, thanks for reading this.
Ive been asked to look at a job where the DNO connection (single phase 80A TT) is a long run to the final circuits. Small feeder box has been installed and the volt drop dictates 95mm cables are needed to take to another feederbox where the feeds into the building...

They seemed to work fine but over the course of a couple months some of the gu10s have gone off, some go out and then come back on.
I was wondering if anyone had come across...
Hi I've been a spark for over 15 years now and recently done the EAL inspection and testing. Signing up with napit too.
Seems to be a load of confusing conflicting information on what your meant to do during a Fuseboard change. With regards to the initial inspection and testing. I've been told...
Hi there. Quick one for you hopefully. Used an mk grid switch dimmer to switch GU10 led lamps. Load is well within the rating but soon as dimmer is on there's a hum. From both the dimmer and other two way switch and also the mcb. Take it out it all stops. The mk instructions do state to not use...
