Well the OP has already stated in a previous post, that the electrical contractor company is paying for all damage, and there is no question that it is their's to pay, so my comments will speak to that.
The damagaged is very likely to go beyond what was described. When the 120v shorepower plug was connected to 240VAC, the transfer switch controller was probably burned out, any TV, VCR, DVD, battery charger, inverter, HVAC sysem (if the T-Stat was not OFF). microwave, on-board WIFI electronics like Cradlepoint or WiFi Ranger, etc. I would make sure that every electronic and electrical system is inspected and functionally tested, before signing off on the damage. If you miss something, you may not be able to go back when it is discovered, and file an additional claim. So check everything.
