You are buying TRC-50-1
The cable is rated for 1kVRMS or 2kV DC.
I cut these from master roll and provide about 5% extra cable length.
You will get 3m or ~10 feet.
if you order multiples you will receive 1 long cable you can cut to your liking.
Example - your order 4 x 3m = 12 m you will get 1 piece that is 12m long.
Thanks for looking.
