Adding multiwire kitchen circuit, I see my neutral bar is already
full- in fact overloaded, with two wires under some screws- this is
incorrect, no? or ok, depending on wire guage? So, planning to add
extra neutral bar, connecting this to existing bar. Can I just screw
new bar to back of panel, or does it have to sit on insulators? This
is main panel, Crouse Hinds model 14 type G, 200A service. I am
mindful of torque requirements, inadvisability of putting heavy loads
on "skinnies" (have to switch a few circuits to these to make space).
I do realize I'm near the limit on this panel. Just not up to
springing for a new one just yet.
