When installing a SolarPV system in a home, many times the point of connection to the main service panel (MSP) is made by tapping onto the service feeders using 'bugs' ("Supply side connection" - see attached photo). (With the other method of connection, by back feeding via an OCPD (breaker) in the MSP.)
Are there any code restrictions that prohibit a "supply side connection" in the existing Main Service Panel? If so, where in NEC2011 (or older) does it state such a connection shall not be in the existing MSP?
Attached photo shows this connection in the MSP, but a local electrician stated recently that this connection can never be located in the MSP, and must be installed between the Utility meter and the MSP.
Thanks for your input, Rob
