I need to put in a dedicated circuit going to the garage part of my shop, 50 feet away.
Lincoln says a 40 amp breaker is required. This would mean 8-2 with ground. I've seen a couple of web sites that claim 10-2 w/G and a 30 amp breaker is more than enough. My neighbor also thought 30 would do it.

If you have to put in an additional circuit and wire it up any way, why not go 8-2 w/a 40 amp breaker? It never hurts to have more capacity. You'll never regret having "too much" but you might wish you had more if you go with just enough to get by.
