I've added a redundant gas pipe to an earth nest. Seemed a shame to waste it.
I would say that's good thinking.

Give the guy a break, He's moderating some of the best educated trolls in the field.
Which reminds me ,,,, Where's Biff??

I got the idea from the first substation I was involved with. Four 8” dia 120’ long continuous welded pipes took the 11KV cables under 2 railway lines and three roads. Where they protruded in to the cable chamber we welded studs on and connected them to the MET.
How was that mate? One or the other surely? What I've noticed a lot recently is that a PME conversion has been done but they've left the old cable to the sheath of the incomer.Got upstairs and it was also a tns and tncs.
Just an off the wall thing for you here Guru; Do you know anything about instumentation with the ABP logo on it?
I'm talking about 20" dials with pointers driven by a Selsyn? unit and had bugin lamps arranged around the circumference of the dial. and Cam switches which were Honeywell micro switches operated by cams driven through> a reduction gearbox.
Another one was a Drum Indicator which was an aluminium cylinder about 4" diameter x maybe 20" long. It was mounted vertically behind a panel which had a vertical slot about half inch wide cut through from top to bottom so you could see part of the drum.
There was a helical line drawn around the drum from top to bottom and one side of the line the drum was painted black and the other was painted red (from memory) as the drum turned - again driven by a selyn - the slot in the front plate would fill from top to bottom either red or black. I believe this was indicating the level of something somewher in the plant.
I used to make these damned things from start to finish including the engraving which was sometimes in Spanish but never knew what the were for.
I think these things were used in the iron & steel making industry.
The first gauge you mention rings a bell. They were used on Canadian Calcamatic kilns. They were towards the centre of the panel which means they must have been part of the combustion control. What for I can’t remember. All the burner control was by Honeywell and GE. Selsyn were part of GE.
The second “thing” I haven’t a clue. I’ve worked on plenty of drum controllers, they used to fascinate me. Both the primary crusher and the washing section used them for auto start up.
Some PLC’s now have drum function blocks. I used them for the electric furnace you’ve seen pictures of. It replaced those crappy cam timers you made.
There’s something niggling me about this controller, was it used for speed control?
I haven't a clue what they were for.
We made chart recorders as as well - paper on a roll like bog roll passing from one roll to another while an inky pen traced a wiggly line on it.
Because I want to know what the "bare minimum" is that will comply for me to be able to upgrade the consumer unit in the house and reconnect the submain. I don't want to tell them that the tenant needs to take a day off work & move all their furniture & all the flooring needs to come up etc. to put a new submain in from the front door to the outbuilding over the back yard IF IT ISN'T NECESSARY!
"What is the point in asking questions" whats the point in the tone of these replies-
"Something is certainly obvious, but i'll limit my comments to the job you are asking about"
"What do you mean by 'especially for a letting agent'? Are their lives worth less than other peoples and so it's ok to install substandard earthing ?"
"To be honest i just can't be arsed"
"He'll probably just bung a twig in and call it a day"
I think you're trying to help but equally you want to shoot me down at the same time haha
Please tell me what would be wrong with the following-
Keep existing 2.5mm submain from 20A 30mA RCBO in house.
Disconnect 1.0mm CPC of 2.5 t&e in outhouse.
Install rod & bonding in outhouse.
Be as condescending as you like if you answer the question
