I picked up an outdoor concert series, and here's the power that is provided.  It's clear that it's a PS-54-HR with a NEMA 14-50.  I looked at lots of sites, and I did not see exactly what I'm looking for.


Thanks!

I knew if I read through this section, I'd find something!  This, from another post looks like it will fill the bill:  http://peavey.com/products/index.cfm/item/964/117526/distro

Any other suggestions, please do!

For outdoor use, you might want to consider using a "spider box" with GFCIs. A spider box is a common construction item, and is probably available at a rental center near you, depending on whether it makes sense to buy one or not. IIRC, a new, made-in-USA spiderbox is about $500. CEP is a well known brand. Construction spider boxes are bright yellow (for visibility purposes) and typically have runners or a roll cage that hold them up off the ground (OSHA compliant and UL listed).  Mark C.

Thanks Mark! 
All of the "spider boxes" I am seeing so far have the twist style plugs -- are the "range" style less common?

The standard solution is to build a short 14-50 to Calif connector pigtail. Because the spider box is rated for 50 amps, you could also build a 14-30 to Calif connector pigtail (but that would limit you to the 30 amp service.)  Mark C.

Edit:  To answer your question, a 14-50 is more common for RV service, but it is not as robust a connection if you are attaching an extension cable.

I ran into one if those at a fairground. I tried a standard range plug and damn if the right angle put the cord up the top. Fortunately for me, I had built the cable so I took it apart and rotated the pin end 180.

So, buy some 6-4 SOOW and put a California female on one end and a straight 14-50 on the other.

The receptacle in the picture is oriented correctly - the ground pin goes on top. It's definitely possible to run into receptacles oriented incorrectly, but I haven't seen too many.

The correct cord for a California or 14-50 is 4/4 SOOW, not 6/4 SOOW unless you're sure you will never plug into a receptacle fed from a 3-phase service and will not run non-linear line to neutral loads. As that's a pretty tall order in our world, the neutral conductor counts as current-carrying, which derates the 6/4 cable to 45 amps.

Jim at the Amp Shop makes breakouts for this very plug.

I have a couple of Jims distro's.  He does good work.  But they won't (at least mine don't) have the certifications that may be a requirement in your jurisdiction.

Jim is recovering from a circuit breaker shortage, he just got another shipment in and is working overtime to clear his backlog.  He's a great guy to work with.

Terry correctly points out that AmpShop products do not carry a Listing agency sticker.  AmpShop can have distros CSA approved, but it's done on a piece basis and requires that the assemblies are shipped to Canada to be inspected, stickered and returned to the USA.  This adds about 35% to the price and needs to be pre-arranged through Jim.

If one must have UL stickers on the devices and assemblies one will probably spend close to 2x of AmpShop's prices at Lex, TMB/ProPower, Motion Labs, Whirlwind etc.
