There's quite a lot going on there!

 

[Wilko]

Can I ask what you've got planned? I think I'd need a nice of tea ...

 

[Tony Barnes]

It all coming out. The rest of the farms in just as much of a mess, we have only just done a condition report.Idealey hell have the supply upgrade to 3 phase the we will go from there, but he's not to keen as electric board cost are rather substantial.
Would appreciate any surgestion if I can't get him to upgrade.

 

[gazdkw82]

i cant even make head or tail of that mess

 

[Harwoodandy]

That looks expensive.....

 

[Tony Barnes]

There's another good one we come across led cable still in use

Looks like a split phase supply from an overhead line voltage between the 2 phases will probably be 480v.
Check voltage between the "phases" to confirm .
L1 to N+L2 to N = L1 to L2 its split phase and will be 480v (some 3 phase boards are only rated for 400- 415v)
Split phase is fed from a centre tapped transformer and conversion by the DNO will be cost prohibitive unless you get a few customers together.

 

[Tony Barnes]

Yes its split single phase and comes over on line TT system. To be honest I can't see him going for the upgrade so we may have to work with what we have got. Good point regarding the rating of the 3 phase boards.
Cheers

I believe MEM used to make a split phase board but not now, we could not find any DB with a rating higher than 415V last year, in the end we used MEM Exel Switches/ switch fuses which are rated 550V for the 480V bits, feeding single phase boards.

 

[Barry White]

A lot of old farms have one large 480v motor usually on a milling machine. (just ask him as often in weird places)

First pic is at my local screwfix. Second pics are from a recent barn lash up. Why do we bother

 

[Rpa07]

Such a shame! They really could have tried harder and shown a little pride!

 

[freddo]

Someone paid for that! Unless it was DIY...

Found this when replacing a storage heater. This is what happens when you connect a 3.4KW heater to a 13A SFCU.
It had been cooking away for years, it only stopped working when the line conductor in the flex burnt off of the terminal.

Sorry for the extra un-edited photo, could not attach or delete images properly, won't let me delete them in edit mode either.

Presumably it could have been fitted with a 20A DP switch instead?

 

[freddo]

It should have been! I fitted a new one with the new heater.

 

[freddo]

Found during a T+I yesterday, extensions into a new 3ph DB. There is so much wrong in this photo, but most of the terminals are 2.5mm size, the conductors in the bottom are 4mm, some terminals have 2 conductors jammed in, heatshrink has been used to cover crimps but has been held in place with tape, there is 16mm in one end of the crimp and 10mm in the other, the blue conductors are tri-rated singles and are not fitted with ferrules,there is no top to the DB and so on.

 

[Wilko]

Hi Freddo- I wonder what the last inspection report says? Will you get the job to fix it? Cheers.

 

[freddo]

This is the first this DB has been inspected, it was fitted last year There are other problems in the DB itself with poor supply cable terminations, unsupported cables, undersized main earth conductor, grossly incorrect circuit labels, no RCD protection on any circuits, missing blanks, neutral and earth conductors incorrectly numbered... Yes we will be correcting the problems. The installation has a 2000A supply and around 90 DBs. We've started testing/inspecting a part of the installation, testing and repairs will continue in stages to the other parts over the next 4 years.
