-I'm by no means an Electrical Engineer but from time to time I have to do your typical DC wiring and soldering. But AC is a completly different beast to me, since I rarely have to interact with it.+I'm by no means an Electrical Engineer but from time to time I have to do your typical DC wiring and soldering.

-That's why this was done: so I can get this information quicker instead of burning stuff down and / or having 230V - or read that as 120V if you leave in 'Murica - rushing though my heart.+That's why this was done: so I can get this information quicker instead of burning stuff down and / or having 230V - or read that as 120V if you live in 'Murica - rushing through my heart.
