Can you explain what's in this box and what it does? The clip and box at the bottom are for our power meter thing, and we have a (really boring) new and neat consumer unit. But inside the meter box, what's what?

Oh, and "rate my meter box" for equipment and tidiness...

The incoming cable from the street is in the bottom left of the photo.
The grey box it goes into is your main DNO (District Network Operator, or whatever is called now) fuse, rated at 80 amps. This fuse is there in case there is a fault within your electricity metre - if this blows, you are in trouble and will need to phone your electricity company.
This is also where your main earth is tapped off the neutral. It looks like a TN-C-S earthing system.
From here, it goes into your electricity meter.
From here into an isolator switch
Then into a junction box that splits the feed to go to your podpoint consumer unit and your main consumer unit
Your podpoint consumer unit contains an RCD and MCB that then feeds an isolator.

Is this what you meant? :)

If you mean the Hager box, can't see part numbers but it looks like an RCD (residual current device - the "you" contact protection) on the right and an MCB (miniature circuit breaker - the cable/device protection) on the left.

Perfect, just interested to know what's doing what in there. I should know this stuff, everyone should know this stuff but when my grandad was an electrical engineer I almost feel ashamed to have to ask!
