I'm down to the wire, and just got some bad news....

We have 2 trees - 50' tall. Each tree has 5 strings of lights. Power comes to 2 GFI's cut into a plywood panel where a basement window used to be - each GFI fed by it's own 20A breaker - thru a mechanical timer.

Old way: 100' NM - conduit sleeve under a snowplowed emergency access driveway to the first tree; 150' NM same path to the second tree. NM terminated with plug on one end - duplex receptacle on the other - suspended above ground and wrapped in plastic. 5 cords to the duplex - multitaps - to feed the individual circuits. Yes - using NM as an extension cord, not anchored or supported.

Town Manager, not Code Enforcement Officer has stated no tree lighting ceremony this year because of electrical hazards.

Is there any code compliant way to do temporary holiday lighting?
