  • Accepts #14-6 AWG Cu or #14-6 AWG Al wire
Murray offers a wide array of thermal-magnetic circuit breakers that are the key element for overload and short-circuit protection of your home's electrical system. To provide additional protection Murray offers circuit breakers to protect against severe electrical shock or electrocution, mitigate the risk of electrical fires and protect against damaging surges and voltage spikes. Circuit breakers are intended for switching and protection of your home's wiring from high temperatures caused by excess current higher than the rating of the wire. While thermal-magnetic circuit breakers are the key element for overload and short-circuit protection of your electrical system, there are potentially dangerous conditions that do not involve over current.
  • Single pole, 20 Amp 120-Volt type MP circuit breaker
  • 10,000 AIC interrupting rating
  • Murray type MP circuit breakers provide easy plug-in connections in Murray enclosures and the time saving insta-wire feature
  • Compatible with Murray rock solid load centers
  • Use for overload and short-circuit protection of your electrical system

What 20 amp breakers are compatible with a General Electric panel

Asked by: Ronco
I would go with a General Electric breaker. They are stock at my Home Depot store. I always try and match manufacture products.

How do you connect the wire to this breaker

How do you connect the wire to this breaker
Asked by: Paul
There's only one wire that connects to the breaker, that's the black (hot) wire. There's only one screw on the breaker, that's where the black wire attaches. There are two bus panels, one for the ground wire and one for the common (white) wire. With the power off, snap in the breaker. Connect the ground wire to where you see all of the ground wires connected, locked in by a screw. Do the same with the white wire, connect where all of the common wires are connected and secured by a screw. Last, insert the black wire into the circuit breaker and tighten the screw. Turn the power back on and test the breaker by tripping it on and off.

Wire gauge spec

The description of this 20A breaker states wire gauge of #14-#16. It's my understanding that #12 is required for 20A circuits. Why the discrepancy?
Asked by: RetiredJoe
You found an error in the description, the corrected wire range is #14- #6. This breaker can be used with #14 wire in certain instances of motor starting circuits. Using #12 minimum with a 20 amp circuit is not a hard and fast rule.

Our breaker popped and wouldn't reset. Yes, we had to replace the breaker and it was so cheap. But also, there was a popped outlet somewhere in the house. We had to move some furniture to find where it was. One of the wires had popped and part of the outlet had melted. Our tenant used 3 AC window units at a time, plus a microwave, although our contract states no more than one AC/heat plug in unit is allowed per unit. It was too much for the 55 year old panel. This for under $4, a new outlet for under .50 cents.. I was back in business in 15 minutes and I had .50 cents left for some gumballs :)
