OK, it's only polite to say "Hi" in return.
I could be considered a fraud on here as I'm not and never have been a contractor. Now retired, I spent most of my working life in aerospace on the design and development testing of military aircraft systems.
The design and construction of engineering test laboratories and facilities involved dealing with high frequency, (400Hz), and DC which can sometimes produce some unexpected results when operated along with domestic supplies for test gear etc. Stray earth currents were a common source of problems.
This type of work developed my knowledge of and interest in installation practice.
I enjoy following ECN and thank the moderators who take the time and trouble to keep it running.
