Reliance Controls Pro/Tran-2 30A 240V 2-space 6-circuit Surface-Mount Transfer Kit — Prewired, 7,500W Generator Support

The Reliance Controls 306CRK Pro/Tran-2 is a fully prewired 30 amp, 240 volt surface-mount transfer switch kit that lets a portable generator safely power up to six circuits during an outage.

When the grid goes down, you want a clear, code-compliant way to feed essential circuits without backfeeding the utility or rewiring your house. The 306CRK Pro/Tran-2 transfer kit includes a 2-space, 6-circuit transfer switch and all necessary components to connect a portable generator (up to 7,500 watts continuous) directly to selected branch circuits. Designed to mount next to your existing load center, it accepts six single-pole circuits or one two-pole plus four single-pole circuits, giving you flexible selection of which circuits to power.

How does this transfer kit keep generator power isolated and safe?

The transfer switch mechanically separates circuit load wiring from the utility feed so generator output cannot backfeed the grid. This prevents dangerous power on utility lines and protects utility workers and equipment. Reliance Controls prewired design reduces installation errors compared with field-built tie-in methods.

• Mechanical transfer prevents simultaneous connection to utility and generator
• Prewired module minimizes wiring mistakes and installation time
• Installs adjacent to the main breaker panel for clear circuit segregation
• Supports up to 7500 W continuous generator output for common household loads

What circuits and generator sizes can I run with the Pro/Tran-2?

The 306CRK accepts up to six single-pole circuits or one two-pole plus four single-pole circuits, so you can prioritize lights, refrigerator, sump pump, furnace blower or other essential loads. It’s rated for 30 amps at 240 volts and designed to work with portable generators that deliver up to 7,500 watts continuous output.

• Configurable: six single-pole or one 2-pole + four single-pole circuits
• 30 A, 240 V rating matches many generator transfer scenarios
• Recommended for portable generators up to 7,500 W continuous output
• Ideal for essential circuits rather than whole-house loads

How easy is installation and what comes in the kit?

The kit is supplied completely prewired to simplify the install and reduce time at the panel. It mounts on the surface next to your existing load center and includes the transfer switch module and required connection components, so a qualified electrician can complete the hookup according to local electrical codes.

• Completely prewired transfer switch module for faster installation
• Surface-mount design installs adjacent to the main load center
• All necessary components included for a standard 6-circuit setup
• Professional installation by a licensed electrician recommended

Will this work in a typical home setup and what limitations should I know?

The Pro/Tran-2 is intended for selective circuit backup—keeping key appliances and systems running, not powering an entire home. Because it’s a 30 A, 240 V switch that supports up to 7,500 W continuous generator output, you should balance loads across the chosen circuits to avoid overloading the generator.

• Best for essential circuits, not whole-house backup
• Requires load planning to stay within generator rating
• Check local codes and have a licensed electrician install the kit
• Not a replacement for an automatic transfer switch or whole-house transfer system

Who is this for? The Reliance Controls 306CRK Pro/Tran-2 is aimed at homeowners who want a safe, code-friendly way to run important circuits from a portable generator during outages. It suits those who need an easy-to-install, prewired transfer solution mounted next to an existing load center and who plan to power lights, refrigeration, pumps, and selected small appliances rather than entire-home systems. If you want a cost-effective, flexible option for critical-circuit backup and will use a generator up to 7,500 W continuous, this kit provides a clear, reliable path to emergency power with minimal panel modifications.
