Product FAQs

7 answers
What equipment is the QGP22150TM circuit breaker designed to fit?

This unit-mount breaker is specifically designed for use in Square D EZ Meter-Pak metering centers, including 225A MPL lever bypass metering equipment.

What does the letter G in the QGP22150TM part number indicate?

The letter G designates the interrupting rating tier within the Square D Q-Frame family. A QGP breaker provides a 65kA interrupting rating at 240V AC. Other tiers in this family include QBP (10kA), QDP (25kA), and QJP (100kA).

How is the QGP22150TM wired and mounted during installation?

This unit-mount breaker features a line-side terminal nut configuration for bolting directly to bus studs in Meter-Pak centers. The load side is equipped with mechanical lugs that accept 4 AWG to 300 kcmil aluminum or copper conductors.

Where can I find the correct torque specifications for the load lugs?

Torque specifications are printed directly on the breaker faceplate label. Always use a calibrated torque tool during installation to ensure safe and code-compliant connections, preventing thermal issues caused by loose wiring.

Can I substitute a QDP22150TM or QJP22150TM for this breaker?

Yes, provided the interrupting rating meets or exceeds your system available fault current. The QDP version has a lower rating of 25kA, while the QJP version offers a higher rating of 100kA compared to the 65kA rating of the QGP. Always verify fault current requirements with a licensed professional before substituting.

What type of trip unit is installed in the QGP22150TM?

It features a non-interchangeable, fixed thermal-magnetic trip unit. This provides standard LI (Long-Time and Instantaneous) protection, meaning the thermal element protects against gradual overloads while the magnetic element responds immediately to short circuits.

Is this breaker compatible with Square D I-Line panelboards?

No. The QGP22150TM is a unit-mount, bolt-on breaker designed for metering centers and individual enclosures. It lacks the plug-on jaw connections required for installation in I-Line panelboards.
