I'd love to chime in on this as someone who's currently using the SwitchCraft connectors for all leads and from my spa panel to my control panel.
If I had it to do over again, I'd probably NOT go with the SwitchCraft connectors again; although these PowerCon connectors address many of the issues that I have with the SwitchCraft connectors.
-I'm also nervous of a spade connector coming lose or touching another spade connector either inside my control panel or cable. Although hard to see in the picture that was posted here, there IS a plastic separator that keeps the connectors separated from one another, it is NOT much of a stretch that two of them might touch together.
These things ARE time consuming (especially the cable connectors) to get right; there's a very small margin of error that you have to work within between the cable sheath and the end of the individual wires so that you'll get a good full-on connection inside the connector and so that the cable glands can crimp down on the sheath; crimping all those spades is also pointless once you see that the PowerCon connectors don't require spades and are just simple "push in and screw down" connectors. You have a DRAMATICALLY reduced risk of two conductors touching each other in the PowerCon connectors, too.
I'm going to buy liquid electrical tape to try and insulate those SwitchCraft spade connectors and try and reduce the risk that two of them will touch and create a dangerous short.
It's also pretty clear to me after wiring a few of these SwitchCraft connectors that they were NOT designed to be used with 10/4 wire as the "boot" (it's what they called it in this video:
) just won't fit over 10/4 wire -I had to grind down the inside of the boot to make the ID big enough to fit 10/4, even 10/3 with a thick jacket (the HomeDepot stuff) was a VERY tight fit and I had to grind it down a little bit, too.
For me the PowerCon connectors move into the realm of being quite acceptable, but I will not use the normal SwitchCraft connectors in my next build.
Again my two complaints are: ease of proper installation, and safety because of the spade connectors.
They are priced fantastically, take up a small amount of room in a control panel, look fantastic, and provide great functionality, but the PowerCon connectors additionally address my two previous concerns and safety isn't a minor one.
P.S. If you over tighten the SwitchCraft control panel connectors even a TINY bit they WILL break; the plastic is very brittle; do NOT over-tighten.
