Our AC products are scheduled to be UL1449 3rd Edition Listed by June 29, 2010. Our new listing will appear on the UL website on that date. In the meantime, MCG has ample supply of UL1449, 2nd Edition Listed (including the requirements of 2/9/07) products. So in either case, you or our customers will receive UL1449 listed products, and there will be no laps of MCG supply with listed products.

The MCG project is massive. We did not submit one or two models for a quick compliance like some manufacturers did. We're doing it all.

We thank you for your patience and invite you to call us any time with questions, comments or sure protection problems.

Sincerely,

Dion Neri

Engineering Manager
