I want to install my own 50 AMP breaker for a NEMA 14-15 outlet. I've never messed with breakers before but I'm comfortable with electricity. I've wired tons of stuff in my own house. Process seems pretty straightforward when looking at DIY guides on the interwebs... however I only have a spot for a single breaker left on my panel and a 50 AMP breaker needs two spots. Does this mean I would have to install a subpanel? Does this make things a lot more complicated?
