You're going to ground a plastic clock? (Yes, I know one "safety inspector" who required it)
You've never heard of "double insulated"?
grounded outlet or not.
You have *no* 3-prong plugs?
Outlets replaced somewhere along the line?
So are modern two-pronged plugs and three-pronged outlets (without using the ground pin).
Grounds are not supposed to be daisy-chained (neither are neutrals).
You didn't get your Obamatelegraph?
I be still waytin on mah winmil an soler sells an den mah Chevy Volt. ^_^
TDD
You can chain a neutral through a device unless it is a multiwire circuit. There is no rule at all about grounding conductors beyond
"Electrical equipment and wiring and other electrically conductive material likely to become energized shall be installed in a manner that creates a low-impedance circuit facilitating the operation of the overcurrent device or ground detector for high-impedance grounded systems." If the device manufacturer provides 2 screws, you can chain through that device. It is common to see the ground looped through the single screw and continuing on to the next one.
I didn't say that it wasn't to code. OTOH, it's terrible practice. An inspector I had would have failed me for using both neutral screws. He probably would have condemned the place had I daisy-chained grounds.
Should have been clearer--I meant extension cord plugs.
So you can use it with your plastic clock.
OK, let me change the answer to "because it's not necessary".
