Is this single or three phase?

[Mr Punter]

I have just found this in some workshops I bought.  I am not sure if it is single phase or 3 phase?  Just a single phase CU connected.

I'm no expert - I would hazard its two phase?  Three phase cable but only two of the phases have been connected up?

Single phase with an old twin fuse head.

 

Let's HOPE the neutral fuse holder has a solid link and only the line fuse holder has a real fuse.

Every day is a school day! What's the purpose of a twin fuse head?

One reason for the question was that I am planning to build 3 flats on the site and the 3 phase supply would have saved a fair bit.

 

I was a bit mislead by the 415V label but @ProDave is all knowing with leccy.

 

I will get in touch with the DNO for quotes.

Can you take a dead square on picture? or even from slightly above?

 

It looked as though the red comes out of the left hand fuse and the right out of the right hand fuse but now I am not sure.
