[RE-wrenches] Generator bonding discussion

[Drake Chamberlin]

Portable generators do not usually ground to a premise wiring 
system.  The neutral and equipment ground bond to the frame.  I don't 
know how safe or unsafe it is, but that is normal operation for these 
machines.   This method is required by 250.34, and is acceptable for 
cord and plug applications, which this is.
