And for me, this will be one of them!
The outbuilding ony had 120v and I need 240v. Like most things, I figured it was something I could do myself
First trip up the ladder to analyze the situation I asked myself (repeatedly) "what in the hell are you doing?". Lack of confidence is the first strike on the risk-vs-reward scale, so off to Menards for a $99 safety harness kit.
With confidence [somewhat] restored (nads in hand), mission was accomplished, safety harness returned for refund
, and doubtful I will tackle something like this again!
I tried to take as many precautions as possible (and yes, I killed the power) before diving in. Which included my son's girlfriend checking on me periodically (and taking photos)
