Is that a DNO or private meter.
You can get screw extractors like this:

However, aside from the obvious aspect of safe isolation before working on it, in practice it is hard to get out a screw that has been over-tightened to the point of breaking the head without breaking the extractor.
If I simply had to get the screw out then I would remove the meter, cut the tail that can't be removed, drill the cable to release some of the pressure, and then try a screw extractor on the head. Assuming it is successful, then try to source the correct replacement screw.
In reality a replacement meter is a much better and safer route, so speak to the DNO/electricity supplier about that as it is not the client's property to change.

To get a screw extractor in there you would first have to use an end mill to flatten the remaining half of the screw, spot it with a centre drill, bore a hole in the centre, a left hand drill bit is best for this when trying to remove broken screws, then try the screw extractor. The meter would need to be clamped down in a drill press or mill to have any chance of success.
That is where the confusion starts, with switched live being called line or phase and visa versa, I reserve phase for the inputs from the meter.
A conductor should not be referred to as a phase conductor, it is a line conductor. Phase denotes a connection between lines. The IET or IEE recognised its incorrect use and amended the Regulations from phase to line.
Is line dancing when you get hold of the phase?
Love the way the original post is shown at the top of subsequent pages now, good mod Dan. ?
We know that, these days, the forum is much stricter post wise, in many instances....but it certainly is not when looking at 'live connection work' and 'metering problems'.
Some would have been 'screaming blue murder' at this thread a bit back.
By the way, I've always been one for 'confidence levels' but sometimes 'over confidence levels' come into play.....and with an open forum????
Please yourselves!

@alex34482 you have not come back on any posts. Assuming that is a DNO meter then your only option is to contact the service provider not only for your own safety but also you should not be interfering with the meter. Thread closed.
