Anyone seen this before?

A two phase supply with separate meters, where each phase passes through a 60 Amp voltage controlled DP leakage breaker?

Is that top one economy 7?

It's the timeswitch for the meter underneath it. There must be another meter out of shot to the left.

I'd call that a bit of a lash-up. I like the way the T+E submain nicks the earth out of DB1, presumably it serves a different part of the same installation? Is it actually a 3-phase incomer or, as I have at my house, two phases of the three on an old 3-wire DC service cable?

Its a 2 phase incomer, I just never expected to see two phases without Neutrals going through the VOELCB.
There are two meters and time clocks.
Even the Neutral for the rhs meter is looped through the lhs meter.

I was reading about some of the methods they used to adapt AC supplies to use the old DC cables the other night, some of it is quite ingenious!
This was in a UKPN document about standardising their network.
The phase/anti phase setup was so simple but ingenious

Made out of two single phase service cables with neutrals paralleled. Odd setup, the looped neutrals make it a single 2-of-3-phase supply rather than two single phase supplies (I don't like calling it 2-phase, that did exist but was electrically different).

I see the timeswitches are supplied from the load side of the meters - aren't they normally supplied from the line side so that the customer is not charged for the timeswitch power?
