garage/bodyshop phase 's not balanced?

[davesparks]

Here we go, i've found a few pics from a job I did a while ago:

Firstly an old one on its way out of the installation, its a single phase + switched neutral version, the three phase is a bit wider with three of the fuseholder units in a row and a separate unswitched neutral block with a screwed disconnect link.
The jobby to the left of it is a three phase changeover/motor reversing switch by the same maker and using the same switch contacts and moving contact bar.
And the big blue things are old stage lighting dimmers (4 x rheostat in a box, each rated at 1000W I think)







And a pic of a very old one and the top half of a new coloured one,

One of the few decent bits of electrical kit that is still fully component serviceable, in what is now a throw away society.

Unfortunately they seem to be starting to make the terminal screw out of cheese though like everything else. And putting this damned pozi/slotted hybrid screws in them.

I don't understand why they didn't just stick with the strong slotted ones they've been using since the dinosaurs left the planet.

Why, ....because like many people here, they ''think'' that New is always better, that and any excuse to cut material costs!! However, we oldies ''KNOW'' better!!
