Questions and Answers for GE Q-Line 30 Amp 1/2 in. Single-Pole Circuit Breaker

A:  It will work on any wire type. Remember that aluminum wiring is more susceptible to fires, so ensure you replace your circuit breaker with the proper amperage.

A:  Yes CU-AL wire rated

A:  this breaker is half the thickness of a traditional breaker and you will need to make sure your panel will accept it (not all GE panels will) The tag inside the access panel will provide you with this information.

A:  This is not a Type THQL breaker, it's a Type THQP breaker. It might replace a Type TQP breaker.

A:  Thank you for your question. As the previous person provided an answer, THQP replaced type TQP but would need to verify the panel model. The THQP unique mounting requires "half tab's" on the buss.

A:  You obviously have a pretty old GE loadcenter. This is a Type THQP breaker and it requires the buss to accommodate it's unique mounting. I think the Type THQP replaced the older Type TQP and that the Type THQP breaker will work, but that needs to be verified by a qualified person.

A:  Can not see your picture, if it is a GE breaker box then it should be no problem. If your box is really old and the manufacturer is no longer in business, take a breaker to a electrical supply house and they will be able to give you guidance.

A:  220 requires a special breaker that trips and controls both legs together.

A:  You have neither 110 or 220 so lets call it what it is, 120 and 240. This is a single pole breaker that delivers power to a 120 volt circuit. For a 240 volt circuit you will need a 2-pole breaker. You posted under a THQP thin (1/2") breaker. The 2-pole would be THQP 220. The full sized GE 2-pole breaker would be a THQL 220

A:  Standard breaker is "Single Pole" and only for 110vac. A breaker designed for 220vac, "Double Pole", will look like two separate breakers tied together by the manufacturer (and listed for such use by Underwriters Laboratories). I sincerely believe that if you need to ask this question, you should not be attempting to perform work better performed by a professional licensed electrician. At risk here is not just causing a violation that not only may cause a devastating loss, but one that would not be covered by your (or your client's) insurance carrier, and in the worst case, can cause loss of life.

A:  220-240vac has to be a two pole breaker, the one you are asking about is a single pole.

A:  You need a specific breaker for 220. It would be a 2 pole unit instead of just a single pole.

A:  220 v is simply 2 of the 110 lines. Actually 120 and 240. You need to buy a 220v breaker for your specific breaker panel. It would be a double.

A:  This breaker will accept #14 to #8 gauge wire. Thanks for the question.

A:  Thank you for your question. The THQP120 20 amp circuit breaker is not rated for 6 AWG. It has a wire range of 14-8 AWG, but 12 AWG should be the minimum for 20 amps.

A:  No, the maximum wire size is #8.

A:  I do not know for sure; but 6 gauge is generally for high power applications...(above 60 amps). I am a DIY guy perhaps you should talk w/ a local license Electrician.

A:  No, and why would you. If you need to use the #6 run then just pigtail a #12 to it.

A:  Why? Legally you can use heavier gauge wire generally, but again.. why would you? And why on earth THAT heavy? I haven’t tried 6 so I don’t know if technically it would fit but I’m more concerned about the missing motivation.

A:  I believe they are. You will see on the breaker

A:  Yes, the lugs on Type THQP breakers will accept either copper or aluminum conductors.

A:  Yes, aluminum wire can be used with it , but be sure to use a corrosion inhibitor on the wire where it is clamped into the terminal on the breaker.

A:  Yes it is #12-8

A:  ‘Tis

A:  No, these ones will not fit. The Myers compatible has sort of a hook while these ones are “push in”.

A:  No, a GE GFCI breaker would be in the 1" thick Type THQL format and not in this 1/2" THQP format.

A:  They do make GFCI breakers but I do not believe they make it in the slim line style. I hope this helps.

A:  Yes they do.

A:  Yes, though I believe it may take a double slot.

A:  I don't know about an arc-fault breaker, but this is a half size unit that will fit into the 1 inch space of a standard breaker. 2 of these will fit into the old 1 inch space.

A:  I think you need to find local help. One never needs to replace existing circuitry unless it’s being modified. Arc fault and gfci need to be installed as needed, not arbitrarily. Again. Inspection would never entail replacing existing breakers. Find a reputable electrician.

A:  This breaker is a half wide breaker so 2 will fit in a normal breaker slot for GE. This breaker is used when all your slots are full and you need to add a new line or 2. pull the original full width breaker and pop in 2 breakers in the same slot. One to replace the breaker you just removed and one for the new service line.

A:  QO breakers don't fit any other panel than Sqare D QO panel. I am not aware of any manufacturer that makes a 1/2 size arc fault breaker.

A:  This breaker you have chosen is a GE Type THQP breaker and it will fit in SOME GE panels, but not all of them. If your GE panel is a 40 space 40 circuit panel the Type THQP breaker WILL NOT fit in your panel. GE makes arc fault breakers, but they only come in the full size GE THQL format. If your panel is full you have two options. One option is to replace the panel with one that has more circuit capability or to add a subpanel fed from this panel. IF your panel is a 32 space 40 circuit panel it will accept the thin Type THQP breaker in designated spaces. Consult the label inside your panel door to see if Type THQP breakers can be used in the panel. If they can be, the next thing you should do is look at the panel drawing to see in which spaces these THQP breakers can be used. A word of caution, some older GE panels had aluminum bus bars and were known to catch fire when using Type THQP breakers.
