Short ****** Connection Between 2 Panels

[mobiledynamics]

I'm not a conduit guru

Generator Transfer Switch
Below it is a Splice/Box

I plan to do 1 1/2 KO between the 2.

Connecting them via a short ****** is all foreign to me.
How *short* of a ****** can I use.
Is it just ******, locknut on inside of each panel and then a plastic bushing.
Help the clueless on this one.

I've seen a recent thread, no plastic bushing but the short ****** was insulated on both sides.

You can buy them a bunch of sizes,you need a threaded ******, 4 locknuts and two plastic bushings

2 On the outside of each panel. Then put them back-back and cinch them up with locknut on the inside, followed by the plastic bushing .

See this other method ?

Those are basically the same thing but made as one piece instead of two. They are probably weathertight also. If your putting them inside it's much cheaper to go with the locknuts and plastic bushings.

 

[gasaxeman]

Those are weatherproof for sure, Meyers hubs we call them here in IL, joine together with a close ******. You could do the same with a ****** with sealing locknuts on the exterior portion and regular lock nuts inside cabinets.
If this is a inside install just use a ****** and 4 standard locknuts and plastic bushings

Curious. What is the purpose of the locknut on the exterior side of the panel - 2 locknuts against each other

Just so I'm clear

bushing - locknut / exterior side /locknut - exterior side/locknut - locknut-bushing

You need to capture the metal housing between the two locknuts......on both ends of the ******. The bushings are to prevent wire rubbing on the ******....

 

[rockwithjason]

is this an indoor or outdoor installation? that makes a big difference on what materials you can use. exterior installs must use weather tight fittings which would put you in meyers hub or sealing locknut territory. interior installs can be dona a number of ways depending on what you want. one of my favorite ways to do this is to use a rigid coupling between the panels and a chase ******* with lock nut on each side. you can also use a close ****** and two locknuts on each side as mentioned

Yeah like that, and the purpose of them on outside is two things, keeps ****** from sliding if you removed one of the boxes and also to make a tighter connection against the box for grounding and bonding purposes.

 

[mobiledynamics]

This is for interior install. Which setup will minimize the space between the options/ advice offered in this thread. What is the minimum size ****** I should use....I want the 2 panels as tight to each other as possible.

You can look for a chase ****** but will prob have to go to a supply house for it. That will let you **** the panels right up to each other

Ok, but then how do you fit the panel covers on?

 

[gasaxeman]

Use a short ****** and 4 locknuts,2 bushing plastic or grounding.
That's it no screwing around.
simplest and cleanest way I can think of.

On the outside use sealing locknuts, or use myers hubs.
