[RE-wrenches] Line Side Tap

[Christopher Warfel]

The intent of the line side tap, was to allow larger pv systems to 
interconnect to the SE conductors and not have to consider the service 
panel. So, I agree with others that the service panel has no 
consideration for what you are doing. The panel is protected by the MSP 
Breaker.  Chris
