So do most LE users just buy the indoor cords and cut off the male end?? That seems to be the least expensive way to go especially if you don't need a grounded cord.
I have 0 ft cords for the outputs and 6ft tails for the input.I do my boxes a little different! I am using a 12x12x6 PVC j-box. I mount 8 duplex recps on the box along with 2 GFCI's. The box has 2 6ft 14-3 power input tails. I have installed a over-sized cover as a drip edge to allow the rain and snow to run off. I have had very little trouble with GFCI trips using this method. The boxes are placed right on the ground. The snow will pile on it and tends to melt around the edges. I leave the power on to the boxes 24/7. With this years LE I plan on extending the DMX "LINK" LED out to the connection plate like I have done in the past on my LOR boxes. I use a standard 2 pin header like the terminate one in place of the LED. I then use a rescued header pig-tail from an old computer to plug into this and solder the leads to the LED. See pictures for more details. Most of these pictures were taken at the ICE Mini in Indianapolis a few weeks a go. Notice the cool Lynx apparel!!KEN
I like your idea of using seperate GFCI's for each channel of each box. It gives the protection as well as making it easier to find a problem when one keeps tripping. They also make ones that mount in outlet locations but do not have the outlets on them, just the set and test buttons. I am using one of that type on my deck light system. They are the same price as the outlet ones and if you are not using the outlet portion then you may want to consider using the non outlet type as they have much less chance of tripping due to water getting in them.
