A few pictures from my phone

[RF Lighting]

Was just going through my phone and I've got loads of pics I must upload.

Here's a few for your enjoyment.

DNO supply with fused neutral

Max demand meters. Anyone remeber them?

On a 100A supply

Busbar chamber trunking

"We've just had a brand new 17th edition board fitted"

This was still spitting out sparks on a farm when I got there.

Intresting way of upgrading a cast iron cutout

Click sockets

Church wiring done by a DI

That's better

Ring final in a pub cellar supplying the post mix chiller

SWL for step ladders?

Have you not heard of busbar trunking before?

Looks like asbestos flash pads in the DP fused cutout.
And first glance can't see whats up with 17th ed board, its a bit messy, but other than that

Got loads more on my phone if I can ever be bothered to post!

Have a look at the tails...

 

[Adam_151]

Not very well marked up... or are you saying it was actually reversed?

Though the use of white tape to denote a phase conductor does predate the board by a good few decades

Often see the use of blue or yellow tape to identify the live on pre-harmonised lighting wiring, while not strictly right at least the installer bothed to mark it at all!

As I've noted before, an alternative approach is that taken by my DNO - to strip back the sheathing a bit too much so as to show the red insulation being used to identify the incoming neutral

Kind Regards, John.

Didn't know max demand amp meters existed. Interesting.

I wonder if any of the modern electronic meters being fitted by suppliers have the ability to report maximum demand? - it would presumably be electronically trivial for them to have such functionality.

Many do John if you're an industrial customer, especially if you're on 'half-hour metering'.

 

[Lectrician]

All modern (and old!) poly-phase meters record max-demand, it is often printed on your bills, especially if you exceed your agreed capacity. You will often recieve a monthly penalty fine based on this.

Quite often hit the button on the meter to check the max demand, and the last reset of the meter when quoting for jobs where you intend to add significant loads.

The old meters like RF's where often accompanied by a similar PF meter too.

Thanks. That's what I would have expected, given that, as I said, it is presumably very easy to implement.

Kind Regards, John.

When you talk of "all modern (and old!) poly-phase meters", I presume that you're refering to industrial installations? My meter certainly doesn't seem to have any such facility.

How did that work with 'old' meters (like mine, albeit only a few years old) which didn't have digital display screens (and which, I presume, don't 'record' anything)? - was there some sort of additional indicator of maximum demand?

Kind Regards, John.

What's wrong with the rcd?

 

[RF Lighting]

There's no fusing down between the ring and the appliance it is supplying.

 

[JohnW2]

What's wrong with the rcd?

No front to enclosure? No strain relief for outgoing cable (maybe also incoming)? Possible IP issue at bottom of enclosure (even when it's front is on)? Ougoing cable looks undersized to be adequately protected by the RFC OPD?

Kind Regards, John.

Ah, I see... thanks.
