Apprentice needs help three plate wiring

[Octopus]

OK I will check the neutral bars in the morning. It is a split loaded board

Lights, cooker, ring kitchen on one side

Smokes, Ring, boiler on other.

Is there a way I can IR the switch line to see if a screw has gone through it?

Did you not do that before you energised the circuit?

What does your mentor say?

Correct inspection and testing procedures prior to energising the circuit would mean that this fault would have been detected beforehand, therefore no protective device would be tripping out. Surely dead testing has been performed before switching the power on.

You are an Apprentice, so i wont question your methods etc, as you are still learning. But what i will question is the ability of your Instructor, he should have let you wire up as the diagram, and checked it looking for faults. He should then have told you it is either OK or not, and if not, he should have got you to look it over to see if you could spot the error/s visually, and if you couldn't he should have helped you. If all was OK he should have gone through the correct test regime, and then finally energise and live test the circuit. These are basic's that you should be getting help with. Have you been taught Safe Isolation, Lock off tag off?

Cheers...........and keep asking,

A long time ago we fired in some T&E for a kitchen ring turned it on, without any tests as we thought our work was beyond reproach, and the RCD tripped out.
Eventually got the tester out of the van and checked the IR of each leg and found that the cable neutral had migrated through the insulation and was in contact with the cpc. Bloody annoying !
I know it has only happened to me once in 30 years. How many of you check the cable before chopping it up into pieces ?

Wiring using 3 plate makes life difficult at the fitting unless it is a ceiling rose, far easier if there is only 1 cable to terminate, I wire every light back individually to either a switch or jb, chopping a deep box it only takes a few extra minutes.

So where do you put the JB's you install?

in the back of the deep switch box, lol

A very good friend of mine had a similar problem, took a lot of head scratching to work it out, turned the colour changed conductor mid drum, so blue became brown and vice versa, very dangerous really, luckily he wired it in the ring not a radial so came to light quickly when testing, although still took while to find

I would say its a switch wire at fault, either at the rose/fitting or switch,but as said if you done your dead testing prior , should have picked it up.
