It's good to know someone from different sphere who may have different way of doing things. . .and probably even better.
I had a 6hr layover at the Munich Airport last year and the section where passengers were waiting had the ceiling being worked on.
I noticed that ninety nine percent of power and lighting wiring were done with non-metallic sheathed cables and color coded. This resembles those residential NMC cables here in US.
We don't do NMC cables for commercial installs here in LA--let alone industrial installations.
The only metallic conduits that I saw there were the stem that hold those pendant light fixtures.
Makes me wonder if it is the general practice in all Germany. I had pictures also of underground wire runs in Vienna popping out of the ground in about 6 inch diameter plastic raceways.
Seems like you use a lot of plastic.
If the above is what you are familiar with ..it would be a radical departure from how it's done here.
Having said that. . .it makes it even more important to acquire the actual field experience.
I love those lighting rods on roof of houses in the countryside.
BTW: There is book titled: American Electrician's Handbook. Electricians call it their bible. It has 2000 pages.
I am Electrical Engineer and I found it useful during my contracting work.
I obtained the HIC license for actual home improvement work, a business i tried to start with eco friendly materials such as sheep wool insulation, cork flooring and organic paint.
As far as the germans and electrical work go, plastic is kind of an obvious choice since it is a non conductor and also it is almost 2020 so plastic has superseded in its mechanical properties for electrical components as far as I am concerned.
Just for interest since I am new: is there a show and tell type of section here and if so any interest in some german electrical stuff with pics and explanations?
