When all else fails in looking for certain items, don't overlook your local Ace Hardware. Spent over an hour searching for a quad circuit breaker that had 40 and 20 amp service. Tried the standard Lowes and Home Depot and at least 6 other electrical supply establisments.
Last call was to my local Ace Hardware. They had exactly what I needed. They told me Westinghouse was bought by another company and the breaker they had should work. Service was great...these folks know what they are doing. Next time, Ace Hardware will be my first call. Way to go!
