I'll keep my issue short and sweet. I bought a 200A Square D panel for my home, from here, plan was to install a meter socket using 4/0, power company would finish install.

They told me if my main panel, is farther than 10 feet away, I need a Meter socket combo with disconnect. I ended up going with a Square D RC816F200C Homeline 200 Amp, it's installed on the outside of the house, my 4/0 now goes from this panel, to my Square D panel in the garage.

I'm getting hung up on if my panel in the garage, needs to be unbonded and treated like a subpanel, or if I can bond the panel, since it's plug on neutral ready and it would make things simple.

Appreciate any insight here.

    PON and bonding have exactly no relationship. You can't bond that, as it's a sub-panel. But it does not make things any more complicated, at all, and bonding would not make it any simpler.

Your meter socket combo is your main panel, since it has a disconnect. Therefore, your garage panel is a subpanel and must not be neutral-ground bonded.


I feel your pain. I myself can only eat vanilla ice cream, because I do not have a dog. Wait what? Those have nothing to do with each other!

"Bonding the panel" and "using plug-on-neutral" are not related in any way whatsoever. You can use plug-on-neutral no matter what.

It seems like your question is, "If I don't bond the panel, where do I put the grounds???" And the answer is an accessory ground bar. Peruse the panel labeling carefully and you'll see a table of approved accessories. One of them will specify accessory ground bars that fit 3-4 sites around the panel already drilled & tapped for it. You are welcome to populate any or all of them.

Then pull the neutral-ground bond and you're all set.

The main service wires from the utility (from meter to main panel are totally unfused - if you put a nail through them it will dead short at up to 2.4 megawatts, or nearly the impact force of the Vulcan main gun on the F-15 Eagle. That's why they require the main breaker to be very close to the meter pan.

That panel (I call that a ranch panel) is a fantastic choice, and you'll be glad you got it. The 8 breaker spaces are a great place for a generator interlock, solar, or outdoor circuits including EV charging.
