Fwd: Re: Electrical Question

[Richard Fisher <rfisher@apci.net>]

UPDATE to last transmission:

Please change the standard voltage rating in the US to 120 volts versus
the previously stated 12 volts.  (Yes, I do understand that some,
but not all, equipment converts the power from 120 and/or 240 volts AC to
9 or 12 volts DC).

Sorry for allowing that typo to get out to the world!
