RANT MODE ON IT ISN'T JUST COLOR TO COLOR PEOPLE! You cannot do safe, competent, nor cost effective electrical work without taking the time to actually learn the craft. IF YOU CANNOT OR WILL NOT TAKE THAT TIME THEN KEEP YOUR HANDS OUT OF ELECTRICAL EQUIPMENT AND KEEP YOUR "THOUGHTS" ABOUT HOW IT SHOULD BE DONE TO YOUR SELF! Incompetent advice is a bigger danger than incompetent work because the bad advise can cause dozens of hazards in multiple places instead of just one or two in one place. I have plenty of experience suppressing and reporting fires of electrical origin, injuries caused by electric shock, and deaths by electrocution. I AND THE REST OF THE NATIONS FIRE AND RESCUE SERVICE DO NOT NEED OR DESIRE ANY MORE! rant mode off.
