It is a great feeling ain't it!!??
I had that 100 foot extension cord when I was spending 3 months cleaning out my shop (big metal building on a slab with 2 garage doors). I could run a fan, a light and a radio.
Being on a limited budget (just plain poor!) it was 3 months before I could set up for breaker box and stuff to hook up to the pole. Got home one day and found the power company tag stating that it was correct and all hooked up. I think 7 seconds later I had installed a little stub box with a quad outlet that now ran a fan, a light and a radio.
But it was a great leap in how I felt about my shop!
Not long before I had a few runs up, 220 for the big compressor, lift and welder. Better radio and fan but was still suffering bad lighting.
Then I got lights...that turned on with a switch! I heard Angels singing!
Outside lights, outside plug for the camper, better inside lights and a couple of drop lights later and I am just damn proud of myself!
