Product Overview

The Square D by Schneider Electric QO 30 Amp One-Pole Circuit Breaker is intended for overload and short-circuit protection of your electrical system. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR. All QO circuit breakers are equipped with the exclusive Visi-Trip indicator. When a QO Visi-Trip circuit breaker trips, the handle snaps to a midpoint position between "OFF" and "ON" and a highly visible, red indicator easily identifies the tripped breaker. This enables you to easily distinguish which breaker has tripped in a load center that may contain up to 42 different circuit breakers. QO circuit breakers have features no other manufacturer can offer. They come in many different sizes and can meet the needs of virtually every function in your home or business. These types of quality, industry exclusive products keep the Square D brand ahead of the competition and are builders' and electrical contractors' first choice in electrical protection.

Customer Questions & Answers

Is this breaker suitable for an electric dryer? Can I use 10/3 NM-B cable wiring?

Asked by: CG
Check the dryer manufacturer's recommendation regarding power source size requirements. Also, most electric clothes dryers require 220VAC 2-pole gang-operated breakers. DonR

Can I replaced a 20 Amp for a 30 Amp

Asked by: john
John, only if the connecting wire gauge is suitable for the additional electrical current. The AWG wire size should be no smaller that a #10AWG. Do not over-current smaller wire sizes. DonR

my circuit breakers have prongs on the back of them to go into the box do these?

there are brass like prongs that go into the breaker box from the breaker. understand my knowledge of electrical wiring is 0. I am just simply trying to replace a 20 amp with a 30 amp so my breaker stops tripping when i have a space heater and the microwave going at the same time. the house was built in 1961 and it appears to have all of the original wiring.
Asked by: slrs
Make sure your panel is a style 'QO' to match the Sq D QO style single pole breaker. Also, beware not to install a breaker sized larger than the ampacity of the connecting wiring. DonR

Can I land 8 gauge wire on this breaker. I know on 10 gauge is required but I have 8 gauge currently installed.

Asked by: Randy
This 30-A breaker typically would have #10AWG stranded copper wire installed. #8AWG wire may be a little tight under the wire lug, but you might make it work. Of course #8AWG wire has more ampacity than #10AWG, but the 30-A breaker will limit the electrical current to the breaker's rated value. DonR

This breaker was the exact replacement required, and it was easy to install; also, the price was very reasonable. There are many fake Square D breakers being sold on the internet for outrageous prices, but The Home Depot sells the real thing for a great low price. I'm very pleased.
