@augiedoggy I've gone into it in detail on another thread so I'm not going to rehash it here. You have my permission to use them on your own equipment if that's what you want to do.
oK so I searched through the switchcraft threads and the only explanation I found that you posted why they were not a good Idea was that you think they are just speaker connectors and using them for power is a "Hack"....well just about every diy build on here is arguably a "hack" no? I mean using a watertank heating element for making beer is just as much a "hack" right??
I try to be professional and stick to the facts and only get answers like the one above where you give me permission to use them?
really? I'm guessing your an another electrical engineer since this forum appears to be full of them?
If it meets code and the safety standard its not a hack even if there are other options out there...
I also found this more useful and practical post...here

"We beat this around quite a bit in the
https://www.homebrewtalk.com/f170/show-us-your-element-housings-pots-how-did-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 Faston® 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"
I will repeat and rephrase my statement... I have yet to find anybody that has used these connectors in an application such as this who has had any real issues with them.... Just a whole lot of skeptisim from those that think they are too small or too cheap or "not heavy duty enough because you cant run them over with a truck"...(WTF?) I only unplug mine to drag my kettle to the sink for cleaning and I have had no issues thus far.
but heres the disclaimer..
YMMV (especially if you want to do a lot of yanking on the cables or "run them over with a truck")
As a budget friend option goes, These fit the bill and do it safetly If you want fancy and more expensive options or you have access to twist lock connectors and have the space on your panel then great!
