Just my $0.02 worth,
Personally I would have put the Main Switch at the other end of the DIN Rail, to save the Meter Tails from cluttering up the area between the N/E bars and the MCB tops.
Mind you, considering that this job only took 2 and a half hours to do, it's not really suprising that it looks so rough. [Linked Image]
By the way, does anybody else here have a dislike for Hager?
I've used them for a while and can't say that I've had any problems so far.
You could use worse.
