This circuit breaker was part of a large order of hardware, wire, and connectors needed for an avionics upgrade. As usual, all the items were received as advertised and expected. The best part though, was that my online order, placed late Friday morning for Will Call at the recently opened Midwest location, was ready for pickup Friday afternoon so I could get started on my project over the weekend! The one item that was back-ordered was shipped free of charge from Peachtree and I had it in hand on Monday! Hats off!, to ACS and to Scott and the rest of the West Chicago Team for the great customer service! Tom Naperville, IL
