DIY: What is this power junction box?

[keithmac]

We used to get rollocked for using grammar such as 'mumering' and 'wors'.

I did notice after I posted it but just couldn't be bothered to edit it .

I reckon the microwave got him, the second time around.

Martindale VI13800 and PU for us up to 3-ph LV. Change to ALS HV for ground power and AGL, then big sticks @ 11kV, followed by Pfisterer Phase Comparators at 33kV.



PROVE your tester (potential indicator, PI) works on a known live source (either proving unit, PU, or another circuit which you know is live, not ideal)
TEST the circuit on which you want to work using your PI.
PROVE your PI still works by testing on PU

Airfield ground lighting. Oh how I hate you. Yet love your simplicity at same time.

Still have 11Kv potential indicator and my phasing sticks . Most of the time I will just use a sub contractor as it's easier . Yes that's lazy engineering I know.

That is the only sensible way to use a multimeter. It's perfectly OK to use one if you use it properly.

Problem is a lot simpler than first thought:

The junction box pictured is actually a simple plug extension, one wire in, one wire out.

It extend the plug socket at the bottom of the unit.

They did this because the plug (as with the new microwave) cannot slip behind the shelving.

So:

I've unplugged the junction box, taken the plug off and removed the microwave and junction box.

I'll get a simple, short single plug extension and be done with it

Glad you are sorted but I would stay clear of them ever again, there were far better ways of doing it than bodging it like that

Well yeah - they installed the socket that it couldn't reach to(!)

Put in by previous owners, but I'll pay attention if I get some builders

They were using flat twin cable, did they put that into a plug?

All they should have done is create a spur off the socket & mounted a surface mount socket behind the microwave, about a 10 minute job.

Some folk make frightening bodges. In my brothers house we found the oven was plugged into a standard extension lead under the units and not wired into a separate circuit.

Not necessarily wrong. We had a big 900mm cooker (albeit with gas hob) that was actually meant to be on a 13amp plug socket. If you did it via a cooker spur it'd be wrong in theory as you'd not be fused correctly

Or...they could have put the socket in behind the microwave avoiding the whole issue in the first place!

That's the funniest bit. These guys put the whole kitchen extension in. Why they put the socket in the bottom then bodged an extension plugged into that same socket up to the is anyone's guess.

Wrong it's a fixed load so as long as the circuit operates under fault ( very different to overload/over current) in the required time it meets requirement . Yes even fan ovens . Reg 433.3.1 (ii) off the top of head .

Most flexed fan ovens are 15A rated so it is not technically permissible to use a 13A plug to BS 1363-2: 1995 inc A4 :2012

I have to say I get a bit concerned when I see threads of this nature, it's always a relief to see the OP still posting as the thread draws to a close.

Microwave could get him yet, when he goes to move it again!!

Pin him to the floor.

Mine came with a 13A plug on it and the instructions said it was (unsuprisingly) to be plugged into a 13A socket.
