I'll count myself in. Done loads of industrial, commmercial and domestic...it's all work.
Just to highlight the differences.
I've done the maintenance and installs at one firm for donkeys years. They were bought out last year and the new owner wanted an office refurb. So they got a builder in, who brought his own spark, obviously domestic....what a joke. Since then the new manager has had them in to move a 400v spot welder. I installed three of them about 10 years ago, fed with 25mm swa. The re route is unbelievable.
There is a separate single phase supply to a cooling pump which I'd wired in swa. They've wired it in T&E tied to conduit into a fcu coupled to an existing socket. Got some photos but can't get the 'insert image from computer' to work.
Back street garage stuff, that.
