Hi Roger, this is Steve Young - I bought the Taylor Dunn cart a couple month's ago. Was wondering if you had a 2" diameter hour meter I could put in my cart's dash. Also, maybe you have electrical controls for this cart I could buy for spares. Thanks.
I'd expect the 110vac or the 220vac to be pretty colse to having 12 VDC if you have a diode and some resistors, since that meter draws such a low current.
Not necessarily. Even if you're thinking about 220VAC + safety ground, the exceptions allowing you to use safety ground as a neutral are rather limited, and I don't think an hour meter is included in them. (Off the top of my head I can only think of dryer lights, and even there I cannot figure out why they don't use a 220V bulb.)
I want to believe that the dryer light bulb exception was included because a complaint that the bulb isn't working might make an electrician check the safety ground. If the hour meter is part of a warranty or maintenance contract then the customer may figure out how to defeat safety ground as a way to save money :-(
