Our take on the 50Ft 50Amp Generator Extension Cord

A 50 ft, 50 amp extension cord built from 6-gauge STW 6/3+8/1 cable. One end has an N14-50P plug; the other is cut bare for hardwiring into a transfer switch, panel or outlet. It suits RV owners and homeowners connecting a portable generator to a house or pedestal. The heavy 6-gauge conductors carry a full 50 amp load over the long run, where thinner 8- or 10-gauge cords would not.

Best forRV and motor home owners running 50 amp serviceHomeowners wiring a portable generator to a transfer switchLong runs from a generator to a pedestal or inlet boxHardwired installs that need a cut end, not a connector
Pros
  • 6-gauge conductors handle a full 50 amp load
  • 50 ft length reaches most generator-to-house runs
  • STW jacket is rated for outdoor and wet use
  • N14-50P plug matches common 50 amp generator outlets
  • Bare cut end suits hardwiring into a panel or inlet
Cons
  • Bare cut end needs an electrician or a field-installed connector
  • Heavy and stiff to coil and move
  • No molded female connector, so it is not plug-and-play
  • Long 50 ft runs still add some voltage drop at full load

Questions and answers

Can this cord plug straight into my generator and my RV?
Only the generator side is finished, with an N14-50P plug. The other end is cut bare, so it must be hardwired or fitted with a connector before it can feed an RV or inlet box.
Is 6-gauge wire enough for 50 amps over 50 feet?
Yes. 6-gauge copper is the standard size for a 50 amp circuit, and the 50 ft run keeps voltage drop modest at full load.
Can I use it outdoors in rain?
The STW jacket is rated for outdoor and wet locations. Keep the plug connection sheltered or in a weatherproof box.
What is the extra 8-gauge wire for?
The 6/3+8/1 construction has three 6-gauge current-carrying conductors plus one 8-gauge conductor, typically used as the neutral or ground depending on the wiring setup.
Do I need an electrician to install it?
For a permanent connection to a panel or transfer switch, yes. The bare end must be terminated correctly, and local code and permits apply.
