IDEAL Industries 30-353XJ PowerPlug® Luminaire Disconnect, Model 103X, 3-Wire, Jar of 100, Pack of 100

It puts a pluggable break in the ballast or driver wiring so a fixture can be de-energized and the ballast swapped without cutting and re-splicing conductors. The Model 103X is a 3-wire disconnect, so it breaks hot and neutral ballast wiring plus the third conductor. Both halves are touch-safe per UL 2459, so the line side stays finger-safe when the connector is separated.

Yes. The 103X PowerPlug is sized to fit through a 1/2 in. knockout, which is the standard fixture and junction box knockout, so you can feed it from the ballast channel out to the whip without enlarging the hole.

Pick by the number of conductors you have to break at the fixture. The Model 103X in the 30-353XJ is the 3-wire configuration, so it handles hot, neutral, and a third conductor such as a ground or switched leg. If the ballast wiring you are breaking is only hot and neutral, a 2-wire PowerPlug is the smaller and cheaper termination; a 3-wire plugged with one port unused is not how these are meant to be installed.

That is what the part exists for. The NEC requires a disconnecting means for the ballast in fluorescent luminaires on indoor grid ceilings, and a pluggable luminaire disconnect like the PowerPlug 103X is the common way it is satisfied, with both halves touch-safe per UL 2459 so maintenance can separate it live-side safe. Confirm the exact article edition your inspector is enforcing for your occupancy.

No tools. The PowerPlug uses IDEAL's patented push-in technology: the conductor is pushed into the port and locked in place. That is the reason crews use these on lamp retrofits, since a fixture that would take several minutes of splicing terminates in seconds.

The 30-353XJ ships as a jar of 100 PowerPlug Model 103X disconnects, which is the bulk pack contractors buy for a full-building lighting retrofit rather than a single fixture repair.

The design intent is that separating the two halves is what de-energizes the ballast, and both halves are touch-safe per UL 2459 once apart, meaning the contacts are shrouded against finger contact. It is a disconnecting means, not a load-break switch for arbitrary use, so normal practice is still to kill the branch circuit before servicing.
