Replace Lugs of DG225NRK Disconnect switch to double lugs

[vertx93]

Is it possible (and safe) to change the lug of the DG225NRK Disconnect switch from a single conductor to a double conductor lug?
Here is the pic of the existing lug and the one I would like to replace it with:

Thank for any advice.

2. Thanks for the picture it makes comments easier
3. Gear mfgs don’t make lugs they outsource purchasing. Check with mfgs literature to see if they offer a double lug

Notice the ’bump’ on the bottom of your proposed lug. It will not fit properly without modification.
I certainly would not use it on a new install.

extend the single wire to a J or terminal box where you ca add conductors.

Thanks for the welcome.
I have been looking at datasheets available online and I can't seem to find a double lug accessory for this device from the manufacturer. I was thinking of just getting double lugs from other sources.

Hi @ptonsparky, thank you for pointing that out. So I'm guessing, if I can find one that has a flat bottom lug, I could use that? Something like this one.

I would change just not to the type with the "bump". If you look closely at the existing lugs you'll see two silver screws, one on each side. Those are to prevent the lug from turning when tightening. I you use a wider replacement lug those may need to be removed.

Hi,
would it be a code violation if I have the same setup but one lug goes to PV Solar and one lug goes to gateway?

Be aware of the height of the top screw of the stacked lug versus the enclosure. I have seen the result when the top screw was holding the maximum size wire and as a result was within 1/8" of the panelboard deadfront.

There's a double lug kit that is intended for a safety switch. would it be code complaint to do 1 circuit going the the gateway and one circuit going to the PV solar? or the double lug kit is only intended for 2 sets of wires?

It doesn't matter.

It is possible but many mechanical lugs are only listed for 10ka SCCR.

My suggestion is just remove the existing lug and connect the incoming wires with nesting compression lugs to the stud.

When you say nesting, is that a set of lugs specifically designed to nest one above the other?

Yes. They are readily available.

In some cases you can stack regular lugs too.

Or get a straight lug and a 45 degree lug. They will stack.

Plenty of options.
