"Not necessarily. You may need to tie the units together with a common
ground. Most of the commercial two-tube units have a ground wire,
attached to a green screw. Just tire the ground points together, then
connect this along with the white and black hot wires, to a common
three-prong outlet."
Thanks, Sandy... that makes sense.
