I agree about the labor rate, which is why I said greater than. My point was many electricians seem to be afraid to bill at reasonable labor rates instead trying to make it up on equipment markup.
When I assembled control panels my customers often supplied the majority of the expensive electronic components, so my labor rate needed to take that into account. When I sold electrical equipment large industrial customers often purchased the equipment like switchgear, MCCs, and panelboards so the contractor's were basically only providing labor and wire.
