What the 306C Pro/Tran 30-Amp 6-Circuit 2 Gets Right (and Where to Keep an Eye)

How the 306C Pro/Tran 30-Amp 6-Circuit 2 Keeps Your Home Powered

First Impressions and Setup Reality

You get a rugged gray enclosure that feels solid right out of the box. The hinge lever actuator clicks with confidence, not flimsy plastic.

Reviewers rate this 4.6 stars overall, and most say installation is straightforward if you have basic electrical skills. The screw terminals accept copper wire cleanly, which makes wiring a smoother task. For a closer look at a similar Reliance 30-amp transfer switch, see our review of the 31406CWK.

You’ll need to mount it near your breaker panel, and the six circuit positions give you room for essentials like fridge, furnace, and lights.

Build Quality and Component Choices

Reliance Controls uses copper, brass, and phosphor bronze contacts inside this transfer switch. Those materials resist corrosion and handle repeated switching without wear.

The normally open contacts mean power flows only when you flip the lever to generator mode. That design prevents backfeeding, which is a critical safety feature for you and utility workers.

Buyers frequently praise the sturdy hinge lever mechanism for its positive, tactile feel. No wobble or hesitation when you move between utility and generator power.

Real-World Performance with Your Generator

This switch pairs with a 30-amp generator inlet, which covers most portable units in the 5,000-7,500 watt range. You’ll power multiple circuits at once without tripping the breaker.

Reviewers note that the six-circuit capacity is enough for typical homes during outages. You pick which circuits matter most, then forget about extension cords entirely.

The X-10 connectivity protocol listed in specs means it’s compatible with some remote control devices. Most users don’t rely on this, but it adds flexibility if you want automation.

Safety and Code Compliance You Can Trust

A manual transfer switch like this isolates your home from the grid when you switch over. That keeps you safe from backfeed and protects linemen working on downed wires.

Buyers with electrician experience confirm the wiring layout is logical and matches standard NEC requirements. You get clear labeling for line and load connections.

One minor note: the product title on the listing says “306C Pro/Tran 30-Amp 6-Circuit 2” but the correct name is “Pro/Tran2.” This is just a labeling quirk, not a functional issue.

Value and Warranty Peace of Mind

Reliance includes a full manufacturer warranty, which reviewers mention as a confidence booster. If anything fails, you’re covered without hassle.

At this rating, 79% of buyers give it 5 stars and another 17% give 4 stars. That’s a strong signal you’re getting a reliable product, not a gamble.

For the price point in this category, the combination of build quality and safety features makes it a smart investment for any homeowner with a portable generator.
