Some different colored electrical tape on the ends of the cables or different colored braided sleeving over the cables would differentiate the cable. Then mark the corresponding outlets on the box with the same colors so you know which cable goes where

We beat this around quite a bit in the http://www.homebrewtalk.com/f170/sho...you-do-212079/ thread. Runs4beer did get this answer directly from Switchcraft: "The connectors are rated for 50 A (for the Fast-on terminal type) and 1500 VAC rms. There should be no problem with the customer's application."

Here's what I posted in the other thread:

Switchcraft certainly stands behind using the HPC (High Power Connector) series for this type of use. In addition to the email cited above, from the product sheet:

Markets
• Loudspeakers
• Power audio amplifiers
• Medical
• Process Controls

From the specs:

High Power Connector, 30 A Current Rating, Silver-Plated over Copper Alloy Contact Material
30 A Rating Per UL 1977 on PC Mount Versions
50 A Rating Per UL 1977 on FastonŽ Versions
1500 VAC (RMS)

I am still a bit leery of power inlets and outlets with the same configuration, but I might consider using the panel mounts as an inlet to the control panel and an inlet to the element. With a NEMA 14-30 plug on the other end of the control panel power cord, and a NEMA 6-30 plug on the other end of the element power cord, even I could not screw that up.

Edit: I could also use it as an inlet to a spa panel with another 14-30 plug on the other end.

Yeah, I saw all that on their website but it still doesn't seem to say they're actually UL approved/listed for AC mains application. I see UL 1977 but I don't have a UL book to know what that specifically entails.

It mainly stems that since Neutrik doesn't recommend/approve AC mains for their speakON, what makes the physically interchangeable Switchcraft version different in this regard?

Excellent. Looks like with that and the manufacturer's approval I've found my preferred connectors.

UL 1977:

1.1 These requirements cover single and multipole connectors, intended for factory assembly to copper or copper alloy conductors or printed wiring boards, for use in data, signal, control and power applications within and between electrical equipment.

Yeah, saw that too but that's just overview. Doesen't say anything about the test methods or approval criteria.

Yeah I was going to use these but it's going to compromise the rest of my systems UL rating. lol

Yeah, lol.

Compare something like a NEMA 14-50 connector and the contact sizes vs. those Switchcrafts. Ehhhh...

whoaru99, certainly don't use anything that you're not comfortable using. They are rated for this application and that rating has been approved by The UL for this application. How does The Underwriters Laboratory go about testing that something will meet the ratings the manufacturer states? I'm really not sure but it's methods are accepted by OSHA for what that's worth...
Are there product out there with a higher rating, more contact area? I'm sure of it, there's a lot of products out there with different prices tags and it is up to you to choose what you want to use in your build by what you're comfortable with and fits the budget.
