RE: (ET) charger - extension cords

["Bob Murcek" <rmurcek geisinger edu>]

By the way, cord coiling is a no-no when significant power, like that 
required for EV charging, is involved.  A coiled cord is an inductor, and 
that will increase voltage drop and heating.

A coworker showed me a cute trick.  If you fold an extension cord in half, 
pick up the mid point, and coil the two halfs at the same time (so that 
both ends of the extension cord stay together the whole time), it's OK to 
use the extension cord coiled because there's now a counter-clockwise turn 
in the "inductor" to cancel the effect of each clockwise turn.

Several years ago I discovered another ET in town by accident. I drove the 
fire truck to a fire in a garage, and when the fire was out, I discovered 
a 
(mostly) coiled up extension cord powering an Elec-trak charger had 
overheated and started some litter going.

It's risky to use an extension on this high a load. Make sure it has heavy 
gauge wire, is no longer than necessary, and is well exposed to the air 
throughout it's length so it can dissipate the heat generated.
