A generator becomes much easier to live with when it can power selected household circuits instead of a tangle of extension cords. This Reliance Controls CRK Pro/Tran 2 30A 6-Circuit Transfer Switch Kit Review looks at the kit as a practical bridge between a portable generator and the essential loads most households actually care about during an outage: refrigeration, lights, furnace controls, internet gear, and a few key outlets.
CRK Pro/Tran 2 30A 6-Circuit Transfer Switch Kit
A strong fit for generator owners who want safer, calmer control of essential household circuits during outages
Installation, panel wiring, inlet connections, and circuit selection for a manual transfer switch involve household electrical work and should be carried out by a qualified electrician to comply with the National Electrical Code, local code requirements, and manufacturer instructions.
Quick verdict: the Reliance Controls CRK Pro/Tran 2 30A 6-Circuit Transfer Switch Kit is a strong option for homeowners who already plan to use a compatible portable generator and want a safer, more organized way to run a limited set of circuits. It is not a whole-home backup solution, and it is not a shortcut around proper generator sizing or electrical work. Used in the right setup, though, it can make outage power feel far less improvised.
Product overview
The Reliance Controls CRK Pro/Tran 2 30A 6-Circuit Transfer Switch Kit is a manual transfer switch kit from Reliance Controls, built around a 30-amp, six-circuit backup power approach. In plain English, it is designed to let a compatible generator supply selected circuits through a transfer switch, rather than backfeeding a panel or relying only on extension cords.
That matters because the most common home-generator mistakes are not usually about buying too little gear. They are about unclear priorities, unsafe connections, and assuming a portable generator can behave like a standby system. A properly installed manual transfer switch helps create a defined, repeatable setup: you choose the circuits in advance, your electrician wires them correctly, and you know what the generator is expected to handle before the next storm outage.
The big appeal here is order. Instead of deciding in the dark which cord goes where, the household can have a small set of critical circuits ready to go. For many US homes, that may be more realistic than trying to power everything. If you are still working through the basic safety issue this product is meant to address, our guide on how to prevent generator backfeed during a home outage is a useful companion read.
As with any electrical kit, current package contents, compatible generator outlets, cord requirements, breaker panel fit, and local code treatment should be verified before purchase and installation. Retail listings can vary, and the name alone should not be treated as a complete compatibility checklist.

Pros and cons
Pros
- More organized than extension-cord-only backup: Once installed correctly, selected circuits are ready for a repeatable outage routine.
- Helps define realistic outage priorities: Six circuits force useful decisions about what actually needs generator power.
- Supports safer generator connection planning: A transfer switch setup is intended to separate generator power from utility power when installed and used properly.
- Good fit for essential-load backup: It suits households focused on refrigerator, freezer, heat controls, lighting, sump pump, internet, or a small number of outlet circuits, depending on the home.
- Useful for drills and repeat outages: A fixed setup is easier to practice than rebuilding an emergency cord layout every time the power goes out.
Cons
- Not a whole-home solution: Six circuits means careful prioritizing, not powering every room and appliance.
- Requires professional installation: The cost and scheduling of an electrician are part of the real purchase decision.
- Generator sizing still matters: The switch does not increase what your generator can safely run.
- Compatibility is not automatic: Your generator outlet, home panel, chosen circuits, and local code requirements all need to line up.
- Load management remains on the homeowner: High-draw devices can still overload a generator if too many loads are used at once.
Performance in real use
The main strength of this kit is not flashy performance; it is making a portable-generator plan behave more like a household system. During a short outage, that can mean turning on a set of preselected circuits instead of dragging cords across wet walkways, cracking windows, or moving appliances around. That is a meaningful comfort upgrade when the lights are out and everyone is already tired.
The six-circuit format is also a useful reality check. For many homes, the best outage setup is not about running the electric range, central air, laundry, and every outlet. It is about keeping food cold, maintaining basic heat if the heating system has electrical controls, preserving communications, running a few lights, and possibly powering a sump pump or medical-adjacent comfort device that has been checked for compatibility. The right list depends on your home, climate, generator, and family needs.
Load planning is where this kit either shines or disappoints. If the selected circuits are matched to a suitably sized generator and the household understands which loads can run together, the setup can feel calm and predictable. If the circuits are chosen too casually, you can still end up tripping breakers or overloading the generator. Motors, compressors, pumps, and heating equipment can draw more power at startup than they use while running, so your electrician and generator manual both matter.
A manual transfer switch also does not remove the need for basic generator discipline. The generator still runs outdoors, away from windows, doors, vents, garages, and enclosed spaces. Refueling still happens only after safe shutdown and cooling. Cords and inlets still need to be rated for the job. Carbon monoxide alarms still belong in the home. The switch improves the connection method, but it does not make a portable generator maintenance-free or risk-free.
For day-to-day outage handling, the best use of this kit is with a written circuit plan. Label the circuits clearly. Decide ahead of time which loads are must-run and which are rotation loads. A refrigerator and freezer may not need constant power every minute, while a sump pump during heavy rain may take priority. For a deeper planning method, see our guide on how to rotate generator loads without overloading backup power.
Durability is harder to judge without long-term use in a specific installation, and buyers should avoid assuming every Pro/Tran 2 kit listing includes the same accessories or revision. What can be said responsibly is that the format is well suited to households that want a permanent, clearly labeled transfer point for a portable generator. The value comes from safer workflow and fewer emergency decisions, not from magically stretching generator capacity.
Who it’s best for / who should skip it
This kit is best for homeowners who already know they want portable-generator backup, have a compatible 30-amp generator setup or plan to buy one, and want to power a small group of essential circuits through a professionally installed transfer switch. It is especially sensible for suburban and rural homes where outages are recurring enough to justify a fixed connection plan, but not frequent or severe enough to make a full standby generator the obvious choice.
It is also a good fit for households that value simplicity under stress. If one person in the home usually manages the generator, a labeled transfer switch can make the plan easier for another adult to understand after a practice run. That matters during overnight outages, storm cleanup, or wildfire shutoffs when nobody wants to troubleshoot a messy power setup by flashlight.
Skip it if you rent, cannot modify the electrical panel, only need to power phones and a router, or want silent indoor battery backup instead of fuel-powered generator backup. It is also not the right answer if your goal is automatic power transfer, whole-home coverage, central air conditioning, or hands-off backup for long outages. In those cases, the better next step is comparing standby systems, larger generator arrangements, or battery-based backup with realistic expectations.
It may also be the wrong fit if your panel is already crowded, your generator output does not match the intended setup, or your most important loads are not good candidates for the six selected circuits. Those are not small details. They determine whether the installation feels useful or frustrating.
Alternatives
The closest alternative is not another gadget; it is a different backup-power strategy. Some homeowners use a professionally installed interlock kit instead of a transfer switch, while others move up to standby backup with an automatic transfer switch. Both paths have their own code, compatibility, and operating considerations, so they should be evaluated with an electrician rather than chosen from a product photo.
If your outage needs are lighter, a portable power station may be enough for phones, laptops, internet gear, small lights, and some low-draw essentials. That avoids fuel storage and outdoor generator operation, but it also comes with clear runtime and recharge limits. If you are deciding whether this transfer-switch approach is too much or just right, our overview of portable vs standby backup power for home outages can help frame the bigger decision.
For households that already own a generator and want selected circuits powered safely, the Reliance Controls kit remains the more direct comparison point. For households that do not want any electrical installation, battery backup and individual appliance planning may be a calmer starting point.
Helpful questions
Can this kit power my whole house?
No. It is a six-circuit manual transfer switch kit, so it is meant for selected essential circuits, not whole-home backup. Your generator size and circuit choices determine what can run.
Do I still need extension cords?
You may still use cords for items not on the transfer switch, but the point of this kit is to reduce reliance on improvised indoor cord runs for selected hardwired circuits.
Can I install it myself?
Panel wiring, inlet connections, and circuit selection should be handled by a qualified electrician in line with local code and manufacturer instructions.
Will it make my generator more powerful?
No. A transfer switch improves how generator power is connected and distributed. It does not increase generator wattage or remove the need to manage loads.
What should I check before buying?
Confirm your generator output, plug type, desired circuits, panel compatibility, local code requirements, electrician availability, and the current kit contents from the retailer.
