Electrical Fittings - 90 versus straight, etc
I'm wiring a gen panel to my main panel and just looking at various fittings,
knockouts on the main panel, pull/splice panel etc.
Just a couple of musings/thoughts
When do you use a 3/8-1/2 Duplex Connector as opposed to just running to 2 1/2 knockouts. This question applies to both a panel or a gang box. Is it preferred to run a single cable to a knockout - and when space or lack of KO becomes an issue, you use the duplex ?
Flex Squeeze Connectors Versus Insulated Squeeze Connectors. They both are the same funtionally. Is the insulated just a ~better~ connector as it has a smoother ID ?
When do you choose a 90 degree connector over a straight connector.
In my application, I'm putting the splice panel RIGHT next to the gen transfer panel. I plan to use the 1" KO on the bottom on both panels. and go out from the bottom and come up. I think the bend radius is the same. Either I have a bend on the 90 or I have a long sweeping bend as it makes a U if I use straight connectors on the bottom of the panel
knockouts on the main panel, pull/splice panel etc.

TBD on the nipples with the panels back to back. I've yet to lay it all out but I think if I use the gen switch I have, it might be constricted on the KO on the side

I don't use either of those types unless nobody in town has steel connectors, so I don't have an opinion on them. I usually use snap-in saddle-bite connectors. Too, too easy to work with and almost never break.

Those snap-ins.....I've asked 4-6 sparks over the years when working on new spaces for my company, and only 1 of them if I recall says that all he uses. The rest say locknuts only, the snaps will find a way to work their way out.
