Question about Square D Qob120 1pole 20amp 120v Circuit Breaker

1 Answer

We have a 15 amp double pole circut breaker that kicks each time it's set to on. We have replaced the breaker, but the sameproblem occurs. The protected circut is listed for a blower. The only blower we're aware of is in the heating system. We have several exhaust fans that work, and the heating fan also works on auto or fan only. Need guidance. Thanks Ken Rohm

    The breaker box has been mapped. The home is new and the labels on the box should match the circut. The label says blower, and I'm familiar with only one blower-the one on the HVAC unit. Should I start there?

    The HVAC has two double pole breakers in the box and two on the unit. These are at least 40 amps. What in the heating system would power with 15 amps?



    Thanks

You first must locate the circuit. If the breaker is kicking, something is not functioning after it kicks. The breaker is designed to kick when it is overloaded, pulling in excess of 15 amps. A grounding problem will cause the breaker to kick as well. You cannot, however troublshoot the circuit until you are aware of what appliance it is powering up. Once you discover what is being fed by the circuit, the wiring needs to be checked for continuity and proper voltage where it terminates at the appliance. If the wiring is good, and your breaker does not kick with the appliance disconnected, then you will have to troubleshoot the appliance to see what is causing the breaker to kick.

Cost for a 200 amp circut breaker


Any home supply store can give you the local cost. An additional cost will be even greater than just changing breakers. You must also change out the incoming service drop conductors. There may also be a need to have the power company's transformer supplying you home changed out. Check it out to be sure.

There is the liquid seeping out of the breakers, it is not water the box is dry and it feels like an oil of some kind. breakers are working and are not hot. i have not seen this before. what is it and what...


It is oil. It's used to extinguish the arc.

When a circuit breaker trips, there is an Arc of electricity made inside the breaker, due to the contacts.
The contacts are instantly brought away from each other.

There are three methods employed to extinguish that arc.

[Extinguish the arc. Non-technical explanation. With out some medium to extinguish the arc produced inside, it would go Z-z-z-z-z-z-z-z-z-z-z-z-zap, instead of z-zap]

Oil, Air, and Sulfur Hexafluoride.

So yes, as long as the circuit breaker doesn't have to trip, and produce the arc inside, it is a working circuit breaker.

Is it a safe unit?

NO

The method employed to extinguish the arc if the breaker trips is leaking out.

Replace all breakers that are doing this.

Average cost for a GE single-pole 15, or 20 Amp is around $11 here. A few dollars more for 30 and 40 Amp, but usually double-pole breakers are used for 30, and 40 Amp.

Why anyone would use a twin 2pole 30am breaker I'll never understand.
There is no way this size breaker could match up in quality to two full size 2-pole 30 amp breakers. If one wants to double up, do it with the 15-20 amp sizes.

Circut Breaker Trips


If the fault were with the product, the breaker would trip right away. You have either a poor electrical connection (power supply) or a weak or undersized circuit breaker. Free standing ranges usually use a 50 amp double pole breaker. Check electrical connections at breaker, range recepticle, and power cord to range to make sure all are tight. (obviously, have breaker off when making these checks)

GFI on cord trips out.


Probable cause is a single pole gfi opposed to a double pole gfi.
* Do not use a single pole GFCI ON A MULTI WIRE CIRCUIT, IT WILL NUISANCE TRIP IMMEDIATELY
Use a two pole GFCI circuit breaker on such circuits.

Looking for 2 15amp single pole pushmatic circuit breakers.


A Google search for "15 amp pushmatic" turned up several links. Here's one for a retailer with new ones and an eBay store with cheaper prices (maybe pullouts):

Did you also check the big-box stores like Home Depot or Lowe's or electric suppliers in your area?

I will try this again i don't think i posted it properly.
On the power cord where it connectes to the dryer make sure the red and black wire goes to the outside screws (L1& L2) the white goes in the middle and the green goes to the dryer cabinet.
If you have the red or black going to the middle one it will trip the breaker.
