Well folks, it's that time of the week again!

This week we have a TP&N cutout.
Sorry about the picture. I had to use my phone again

TP&N?, is it Three phase and neutral ?.

TP&N?, is it Three phase and neutral ?.

Al

SP+N
single pole and neutral (single phase)

TP+N
Triple pole and neutral (three phase)

 

[RF Lighting]

But basically yes.

TP&N = Triple pole & Neutral which is a 3 phase supply with a neutral

a TP supply is a 3 phase supply without a neutral

There is something not right with the photo, but I'll see who spots it before I reveal all.

insulation burned off that stranded cable? or is it unravelled SWA armour being used as earth?

cables to earth block look curiously large - is it a home-made TNC-S?

there appear to be 5 fuses/links which is one more than usual
the right-hand one looks like Neutral, but I can only see Line coming out of the middle fuse.

I can't see an incoming cable, where is it?

 

[333rocky333]

Is there two black DI cables clamped on the supply cable

 

[Lectrician]

It is very difficult to see in the pic because of the poor quality.

There looks to be a fourth henley fuse on the far left which is either supplying or is a feed from a split concentric cable. You can see the concentric blacks going up and around to the neutral, and the earths, which looked sleeved or lugged to a cable, connecting to the sheath of the supply, which enters far right.

 

[daytona]

someones strapped the earth from the split con onto the sheath of the incomer,cant tell where the neutrals go

 

[daytona]

is that a PME as in a DIYPME and unfused?

also there is five cutouts so something not right there and only single phase coming out of it.

just wish i was there,would be so much easier

Thats about it.

It's a TP head in a commercial premisis, although only 1 phase is in use.

There is then an additional fuse taken from the head which supplies a flat adjacent to the shop.

This is wired in a split con cable which is badly terminated into the head.
The earth is in a bit of black sleeving, which connects to the incommer cable. The earth for the TP install is a DI black 16.0mm² cable sweated onto the incommer.
