50 amp sore cord question

What kind of heat is produced, with this cord rating, while coiled?

Most wire ratings are for wire IN A WALL or Conduit,, The RV cord is rated for wire in air,, Better heat dissipation.

while i tend to agree w/ you, on external cords/extensions the jacket type also plays into the rating.

Are you really going to be pulling a full 50 amps near continuous? How long is the cord?
Maybe you need #4.... I think the 45 amp rating will be a non-issue.

I believe 45 is plenty just wondering about the rating.

I've already got about thirty ft of 6/4 soow cord but it's rated at 45 amps. Just wondering why the stw rv supply 6/3 + 8/1 is rated 50 amp maybe less copper in the jacket because of smaller gd.
6/4 stw and soow are rated at 45 amps.

ill have to check the jacket stamping to confirm.

I've never seen more than 30A draw per leg. My wife can trip the breaker (on 30a shore power) when we have both AC's, her blow dryer and the coffee maker on.

I built a 50A (75ft) extension cord using 6/3 8/1 and found it in an SOO jacket rated for 600v & 50 (or more iirc) amps...it was almost as expensive as my basement electric cooler :o

I could have bought TWO 30ft extension cords from camping world cheaper but i didn't want the connections laying in wet grass at my in-laws

I think we have the amperage issue covered but I'll post a caveat about making a 50 amp cord. Unless you have some special need to make your own cord (distances involved, unique connectors, etc.), buying an off-the-shelf cord is going to be less expensive. I went through this exercise a couple of years ago and by the time you pay for the correct wire and connectors, a retail cord is less cost. I got lucky and found a Marinco cord at Camping World on the clearance table. It cost about half of what I was going to pay just for the wire.

Thank yawl for your help.
