In many situations, certain kinds of line isolation are required to get UL approval for a product. It is often easier, and cheaper, to buy a power cord with a brick on it that already provides it (isolation) and is already approved by UL than to go through the whole process of dev. your own. -- ------------ ---------------------- Ben Liberman magik@chinet.chi.il.us
