jbrunson Report post Posted September 13, 2015 Can anyone provide the NEMA spec for the end that plugs into the coach? Somewhere in the past ours got whacked down to about 24" long. To overcome this, a huge gauge piece of 4 conductor SO cord was made into an extension cord. I would like to make a much lighter one up about 15' long with #6 4 conductor SO. This moose is big around as my wrist and 40 foot long. Share this post Link to post Share on other sites
kaypsmith Report post Posted September 13, 2015 While putting together my coach, I found that one can buy 15 to 45 foot 50 amp extensions on ebay at some great prices. I used a fifteen foot, cut the female end off, wired it directly into the transfer switch, leaving the fifteen feet to be rolled up, I also carry an additional 15 foot, and a 30 foot extension neatly rolled in an adjoining bay.

Seems that Walmart has the best price just now. I would just like to know what that end is; the extension cord connects inside the wet bay and occasionally causes GFI outlets to trip. I would imagine the wire would be good for 150 amp at this size, smaller would be easier to deal with. Share this post Link to post Share on other sites
wolfe10 Report post Posted September 13, 2015 The problem is that there are a number of different (and acceptable) coach ends. As long as they are 4 wire. of proper gauge and either waterproof OR located inside, they can be used. If you describe what yours looks like/ post a photo, we can be of more assistance.

jbrunson Report post Posted September 13, 2015 Just want a longer one to get the connections away from moisture. The connector is labeled "Marinco". No clue if it is original or not Share this post Link to post Share on other sites
wolfe10 Report post Posted September 13, 2015 Marinco is a very common RV/marine cord and connection manufacturer: http://www.marinco.com/en/products/connect/cordsets/50-amp-125-250v Share this post Link to post Share on other sites

wolfe10 Report post Posted September 14, 2015 From your description, I believe this is the connector by itself: http://www.amazon.com/Marinco-6364CRN-Electrical-Connector-250-Volt/dp/B000NI020W/ref=sr_1_1?ie=UTF8&qid=1442194278&sr=8-1&keywords=marinco+6364crn Share this post Link to post Share on other sites
jbrunson Report post Posted September 14, 2015 Just choking on the price... I made my last 100' 30 amp extension from scraps I picked up on job sites and $25 at lowes. Share this post Link to post Share on other sites
