Members Tomm Williams Posted July 20, 2014 Members Share Posted July 20, 2014 Is 8-3 soow sufficient or should it be 6-3 ? (100ft run ) Link to comment Share on other sites More sharing options...
Members Axisplayer Posted July 20, 2014 Members Share Posted July 20, 2014 At least 6 and some folks will tell you 4. Link to comment Share on other sites More sharing options...
Members RoadRanger Posted July 20, 2014 Members Share Posted July 20, 2014 Hope you weren't purposely leaving out that fourth conductor for ground? Link to comment Share on other sites More sharing options...
Members Tomm Williams Posted July 20, 2014 Author Members Share Posted July 20, 2014 Yes I did!! So I guess the question is 6/4 or 4/4 Link to comment Share on other sites More sharing options...
Members fdew Posted July 20, 2014 Members Share Posted July 20, 2014 50 amp 220 single phase with a neutral and ground over 50 ft 4/4 (55 amps.) If it was under 50 ft you could have used #6 http://www.stayonline.com/reference-circuit-ampacity.aspx Link to comment Share on other sites More sharing options...
Members Pro Sound Guy Posted July 21, 2014 Members Share Posted July 21, 2014 Hundred feet of 4/4...there is some lbs Link to comment Share on other sites More sharing options...
Members Axisplayer Posted July 21, 2014 Members Share Posted July 21, 2014 Hundred feet of 4/4...there is some lbs and some $$$. My 40ft 6/4 with cali plugs was over $250 used and it was a good deal. Link to comment Share on other sites More sharing options...
Members agedhorse Posted July 21, 2014 Members Share Posted July 21, 2014 6/4 is good for 100'. #4 won't fit or be legal with most connectors. Link to comment Share on other sites More sharing options...
Members Unalaska Posted July 21, 2014 Members Share Posted July 21, 2014 When using 8/4 for 50' you have do derate the box to 40 amps? I read something about it somewhere. Good thing I'm not an electrician. 6/4 all the way Link to comment Share on other sites More sharing options...
Members mshifflett Posted July 21, 2014 Members Share Posted July 21, 2014 6/4 will do it, we use it all the time for up to 100'. Just be sure your supply circuit is as advertised. Link to comment Share on other sites More sharing options...
Members Audiopile Posted July 21, 2014 Members Share Posted July 21, 2014 I'll suggest that 6/3 8/1 is seemingly common for up-to 100ft. runs... the 8/1 is the earth ground conductor. Link to comment Share on other sites More sharing options...
Members mikekars Posted July 21, 2014 Members Share Posted July 21, 2014 It seems like 6/3 + 8/1 (for ground) is often indicated as acceptable where 6/4 is. That can be a little lighter and less expensive. But don't be tempted by the good prices on the SJT stuff marketed to the RV folks. Those jackets are really thin and easy to tear. SOOW all the way!

Members srp72ee Posted July 21, 2014 Members Share Posted July 21, 2014 The 6/3, 8/1 is common for installed wiring. I've not seen it for SO cord. Link to comment Share on other sites More sharing options...
Members mikekars Posted July 21, 2014 Members Share Posted July 21, 2014 Here is an example 6/3-8/1 SOW branded by the folks making the most commong spider boxes (CEP) http://www.amazon.com/CEP-6400M-Temporary-Power-Cord/dp/B0012N9UHI Ericson also markets one: http://products.ericson.com/item/bution-50-amp-oscar-power-feeder-cords-accessories/accessories/pn-1504 In my (limited) experience the genuine Hubbel brand cord ends are worth getting. I have one cord with ends from Marinco (a lower end Hubbel line). These are harder to assemble, not as well designed, get out of round easier, harder to connect, and just generally feel cheap. When you are working with 220V / 50A you don't want to mess around with inferior components. Due to their weight and awkwardness and where they are typically deployed, these cord assemblies get banged around a lot and generally abused by all. I would seek out a used Hubbel connector over a new lower grade one. Link to comment Share on other sites More sharing options...
Members agedhorse Posted July 22, 2014 Members Share Posted July 22, 2014 6/3-8/1 is also very common. I haven't had any problems with Marinco. Link to comment Share on other sites More sharing options...
CMS Author Craig Vecchione Posted July 23, 2014 CMS Author Share Posted July 23, 2014 Here is an example 6/3-8/1 SOW branded by the folks making the most commong spider boxes (CEP) http://www.amazon.com/CEP-6400M-Temp.../dp/B0012N9UHI Ericson also markets one: http://products.ericson.com/item/but...sories/pn-1504 In my (limited) experience the genuine Hubbel brand cord ends are worth getting.

I would seek out a used Hubbel connector over a new lower grade one. Hubbell and Marinco are competitors. Hubbell has a competing brand, Hubbell Marine Electrical Products. Their offerings are first-rate, as are those from Marinco. I personally had several Marinco cordsets over the years I was in boating, and the ends never leaked or failed, and the jackets never suffered any problems. But these products are designed specifically for the marine environment and may not be suited to the different set of circumstances found in portable sound reinforcement production. Edit: It should also be noted that both companies' (Hubbell and Marinco) marine shore power cordage is type STW and STOW. Marinco's ParkPower brand RV cordsets are also STW/STOW.
