Good choice!!

This is the second time we have purchased from Breaker Hunter, and both times the Circuit Breaker arrived in better condition than I expected. Good service

Nice Surprise

I was skeptical at first, they had the breaker I needed, priced fairly, and it shipped timely, well packaged, perfect condition (new). I give them an A+.
