I need to add one more power outlet to my garage. The wiring for the existing ones uses 14-2 gauge solid wire. I have an entire role of this, worth of $60 which I don't entirely need but I bought it this way because I thought I would, and it was cheaper by meter/feet than buying exactly what I needed. Later on I discovered that I could buy "primary wire" (auto cable, seems to be stranded) for a much lower price.
What I need to know is what would be wrong if:
- I use auto primary cable instead of 14-2 gauge
- I mix the two (connect the stranded to non stranded)
In terms of intended purpose, the power outlet would be used to connect power tools if I need to work around my garage or if I need to work on my car.
