4.6.3 Insulation resistance (M103).  After the completion of the specified 
conditioning period (see 3.3.3), measure the insulation resistance between 
each circuit and every other circuit, not connected by design, and to 
ground (defined in 3.3.3).  The insulation resistance measurements shall 
be made, using an instrument having the minimum requirements specified in 
4.4.3, in accordance with the following tabulations. Any measured resistance 
less than 500 megohms shall constitute a defect.
