Can I use an extension cord with this product?
MET requires that all manufacturers put the extension cord statement “Do not use with extension cord” on every item that is MET listed by UL 499 standards. This is because they cannot test every extension cord on the market in conjunction with our products for safety. Also, MET suggests that an extension cord is not recommended as a permanent fixture and should only be a temporary solution when using any electrical product.
