All depends -
C - H -- We know as Cutler Hammer
C - H -- Industry knows as Cheap and Handy, also common name recognition
SquareD - Good gear, and last one to go "overseas" with their plants, kind of pricey but nice when spec'd. Did I say name recognition? Would have to live in a cave not to have heard of them!
Murray - Couldn't say either way, we don't see a lot of them in Alaska like the other two.
Siemens is the third on the list up here.
C-H has all the screws in the panel "pre-set" to land wire so no time wasted backing screws out, or looking for lost screws. If customers ask about the C-H name over Square Dog, I just same better gear at a more competitive price
