Picture of the week

[RF Lighting]

Well its that time again folks, this week we have a CU with a loose screw connecting the neutral bar together.


The load was relativly light as the CU fed a portakabin.
There were 2no. 2kW panel heaters, 3no. 4' fluorescents and 4no. twin sockets.


You can see where the burning has been painted over on the trunking and ceiling

Thats only recently been installed hasn't it with the new colour feeder.I notice the brown has been sleeved red.

Apparently the portakabin was bought from A plant about 2-3 years ago.

Don't know how long it had been in service before that.


I assume in was not in this state when the new feed was fitted.

I had a call from someone who was complaining their alarm system had a fault. It turned out that the neutral bar hadn't been tightened up at all. When I asked when the CCU was fitted, they said 6 months ago. When I told them the alarm battery hadn't been charging properly because they had been running the house on 120v they asked if that would explain why their cooker didn't work properly! Tighten all screws - INCLUDING FACTORY ONES!

Why was the house running on 120v sparkyspike?

Wow!

That's really strange, man! [He says, in a Nigel Planer kinda way]

I had one last week that had almost identical damage. Was a Wylex split-load NH, where the split neutral bar had burnt out. Looked like a loose connection.

Funnily enough (or not if you're in the householder's shoes), the previous 1960 Wylex Standard board did the same thing, but it had an excuse (old age!)

That was how much volt drop the poor connection caused

So come on, who recognises their signature on the circuit schedule?
