If you can find these in the right size, put one on the inside and one on the outside of your fitting.

This is at my Home Depot. Will it work?

There are other knockouts on the bottom of the panel.

Cool guy, if you are really compulsive about whole house surge protection, then you should call your POCO and have an under meter Type 1 SPD installed. Having more behind the meter Type 1, 2 and 3's down the line won't hurt either.

Can I use this instead?

Certainly, if you can find the right size.

My dumba** has no idea how to install this thing though ha.

Do you use it on the inside of the box or outside? Everything else seems straightforward, but I’m struggling with how to do the bushing haha.

 

[chandler48]

Use the rings on the inside AND outside, sandwiching the fitting so it will hold in the opening.

Thanks. And will there be any “grounding” issues or concerns since my panel is painted?

Lastly, this product would be easier to install, but I have to assume it doesn’t provide the same amount of protection as the Siemens.

 

[chandler48]

As stated earlier, the ones inside the box are not as good at the external ones. Stick to the external one. No grounding issues.

Yeah, the hole going into the main panel is quite large…the 3/4 size is what I need to use with the surge protector, but they may have used the larger knockout…can you explain how I use the bushing to make it the proper size?

Did you see the breaker I linked in my original post? I have to assume that is the correct 2 pole breaker for my CH setup. Thanks for confirming the left side is better…wasn’t sure if I should do it just beneath the main breaker at the top.

This is the main panel outside which has the meter. Full pic included below.

The feeders go through the wall to my subpanel in the garage.

Does the pic I provided help?
I read the Siemens one was the best out there. I also have a CH breaker setup, I don’t believe the one you linked will work with my system.

Thoughts?

What are you talking about? When I had my feeders fixed (in the subpanel in my garage) the electrician went outside to the main and checked the feeders. No nicks and he made sure they were torqued properly.

Got it now.

Your first pictures missed the main.

@Sberry what does post #13 have to do with the OP's situation?

That type of reducing washer (we use to call it Chinese money) is not considered water tight.

They could be used on the bottom of the panel, but not on the top or sides.

Note the existing one has a gasket.

Can the surge protector be mounted underneath the panel?

Looks like there are knockouts you could use.

If you really have to use the 2" hole in the side, you will need a 2"water tight hub and a 2" to 3/4" reducing bushing.

The connection does need a waterproof hub. You are below the energized parts.

 

[lenaitch]

Out of the box thinking (pun intended) but can the device be installed inside the box? There certainly seems to be the room.

 

[Jim Port]

The protector is not for use in the panel

Have you checked with the POCO about surge protection? Here they will install one outside at or in the meter and charge $5.99 a month. Then they own it and replace it as needed. Surge protectors do not last forever.
Give them a call and see.

There is no better surge protection than right at the meter. My POCO installed one for a reasonable amount <$250. POCO installed and it has a light and sound warning if there is a problem.

Also when I installed my solar system they upgraded my transformer can from 15kVa to 25kVa without charge and to boot installed an SPD right on the can hanging on the pole. POCO lineman said just watch the can and if the SPD looks bloated just call us. LOL gotta love it. Some POCO's are better than others....I think I got a good one.
