[RE-wrenches] Multiple wires on Breakers

[Ray Walters]

So if the lug is the plate type with a screw through the middle, then 
wires can be inserted on both sides of the screw (using the correct wire 
size of course).  I'm assuming this would apply to other brands (GE , 
Siemens) with that type of plate connector as well.  Any other breakers 
out there that might allow double lugging, or other types of splices 
besides uninsulated ILSCOs?  For larger wires, I've used an insulated 
piercing type tap, but I haven't seen those for small ga. wires like for 
adding a lightning suppressor.
