Help making room on 200 amp panel for 50amp breaker
I would go with a larger panel, it looks like you could add another quad breaker since the existing panel is a 8-16 but you are out of space again, to save some $ I would add a sub and move some loads over to the sub and feed from this panel that would save some $ and require less rewiring and the need to bring everything up to current code that is usually required for a complete panel replacement. Personaly with the very small panel you have I would bite the bullet and replace it with a larger 40 or larger slot panel. It looks like the existing loads plus a new 50 you would probably be ok with a 200 but we would need to know the needs like what type heating, water heater and range / AC? Is used in the home.
