What would you like to do?
In a new house with only the standard outlets in the garage on a 20 amp breaker what is the biggest breaker you can put on the circuit?
Could you clarify the question please.
You can't just upgrade the breaker. Its calculated on wire size and other things. You'll have to run different wire if you want to up your amps.
Was this answer useful?
Thanks for the feedback!
Yes, but the 60A breaker will trip when your house box reaches 60A draw. I would not recommend it.
15 amps x120 volts =1800 watts. NEC requires you not exceed 60% of the load. Therefore 1800 x .60 =1080. 1080 watts divided by 120 volts = 9. You can safely install 9 outl…ets on each 15 amp circuit but no more. This is assuming only those 9 outlets will be on the circuit and no lights.
As long as the light circuit isn't over 20 amps.
If there is nothing else on the circuit then you could easily install 15. If there are outlets on the same circuit then try and keep the total of outlets and lights to a maxim…um of 15. But in reality the number of devices depends on how many amps each device pulls. Add up the amperage of the recessed lights you are going to install and then add any outlets and what may be plugged into them to get the number you can install. A 100 watt light bulb will draw about 1 amp. So you can easily have 15 on a 20 amp circuit.
First off there are instances when you can have only 1 outlet on that circuit. If it is powering a microwave, refrigerator, washing machine, garbage disposal, dish washer,… or freezer then that is all that can be on that circuit. But I assume you are talking about a room circuit. By code 1 outlet can cover a 12 foot area. That is 6' on either side of the outlet. So a 12' x12' room by code needs at least 4 outlets, 1 in the center of each wall. If a wall is over 2' wide it needs an outlet. You can put as many as you want up to a point. It really depends on the load on that circuit. I like to stick with the 12 rule and never install more than a combination of 12 on each circuit. That 12 is a combination of lights and outlets. So if you have 10 outlets and 2 lights you are safe. It also depends on what those outlets are powering. If for instance they are powering hair dryers, curling irons, cloths irons, etc then they pull lots of power. So something like a bathroom should be on it's own dedicated GFCI protected circuit even though it may have only 3 or 4 outlets. A bedroom on the other hand does not pull lots of power so you could easily install a combination of 12 lights/outlets. I cannot cover all scenarios in this short space but use common sense and do not overload the circuit. The main restriction is that the total load must not exceed 20 amps and preferably 80% of that which is 16 amps.
What size copper wire is needed to be used for a 120 volt outlet placed 56 feet from the house to a garage that i am wiring and should it be on a 15 amp or a 20 amp breaker?
I would use 12-2 with ground (Black, White, Bare). and use the 20 amp breaker. You could use 14-2 with ground and use a 15 amp breaker. It depends and what you are putti…ng in the garage. We are also required by code to put GFCI outlets in garages. If you are putting the wire in the ground you need to use 12-2UF or 14.2UF which is made to be buried underground.
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
For the US, the two common values are 15 and 20 amps, with 20 being the most common in newer homes and 15 more common in older homes. Which one is used is determined by what s…ize of wiring is run. 15A breakers feed 14 AWG wire, and 20A breakers must use 12 AWG or larger. If you simply replace a 15A breaker with a 20, you will create a fire hazard.
The answer is, yes and no. Yes you can physically pull a 15 amp circuit breaker and install a 20 amp circuit breaker into the same slot on nearly all modern electrical distrib…ution panels. No, if the wiring is only 14 gauge then the potential exists to use more amps on the circuit than the wiring was designed for and you could be creating a hazard including fire from hot and shorted lines. A 20 amp circuit require no less than 12 gauge wire. If you are having a problem with a 15 amp circuit breaker that cannot be resolved by replacing the breaker with another 15 amp circuit breaker, it's time to research why the breaker is tripping to start with. If it's tripping because there more than a 15 amp load, it's time to shed some of the existing load on that circuit.
Never upgrade the circuit breaker's amperage unless you have first upgraded the circuit. A 20-amp breaker will pop before a 12-AWG wire will melt. A 25-amp breaker cannot be r…elied upon to protect that same 12-AWG circuit.
Answer for USA, Canada and countries running a 60 Hertz supply service. Builders generally hook up to 8 outlets and/or lights per circuit. Builders should not be doin…g electrical installations. In Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit. A 15 amp breaker can supply 1800 watts total for lights, outlets, etc. (15 X 120 volts= 1800 watts). As a rule of thumb leave 20% "spare" in the event you connect a power hungry item - 1440 watts total. Add up the total wattage of items you plan to plug in to the circuit. This only applies to commercial properties. There is no strict limit on how many receptacles can be connected to a 15 amp breaker in a residential property according to the NEC. The device is a convenience outlet and they are placed for convenient access to power without creating hazards [crossing doorways, etc]
yes, It does not exceed its rating No, The breaker rating exceeds the rating of the 50 amp outlet. The outlet is designed for a maximum rating of 50 amps. To trip the bre…aker the outlet would have to go 10 amps over its design. You can downsize the 60A to a 50A breaker to comply with the electrical code. The wire connected should be a # 6 which is good for 60A so it will handle 50A nicely.
Depends on what you have connected to the circuit. It is less than 10 amps or the breaker would trip. A rule of thumb is you design for about 80% load related to the breaker. …For 20 amps that would equal 16 amps.
No. Receptacle is rated at 15 amps and the wire that feeds it will also rated at 15 amps. Since it will take 20 amps to trip the breaker the wire will be become overloaded. T…he above is true only if it is a single dedicated outlet. You can use 15A duplex outlets on a 20A circuit, ie: kitchen and dining room outlets per the National Electrical Code.
Can you use a 15 amp 110 outlet on a 20 amp circuit as I am replacing my old outlets with new duplex ones and realized that three of my Kitchen outlets are on one 20 amp breaker?
Yes, you can use lower amperage outlets - the problem would come if you were trying to run a 20 amp appliance on a 15 amp circuit or plug a 20 amp appliance into a 15 am…p outlet. It would be better, though, as some kitchen appliances could exceed 15 amps (toaster ovens, some coffee makers, electric griddles, etc.) could try to draw more than the 15 amps your outlets are designed for. Perhaps you could get some 20 amp outlets and use those 15's in a hallway or something less likely to have high amperage draw.
If you are referring to a cloths dryer, the answer depends on the requirements of the dryer. Most dryers require AWG#10 wire with a 30 amp fuse. If the wiring is AWG#12 then u…se a 20 amp breaker but never use it on AWG#10 which requires a 30 amp breaker. If you are referring to a hair dryer then yes a 20 amp breaker is fine.
Really depends on the load you are going to have on this circuit.But a general rule of thumb for a bedroom, living room, dining roomis no more than 13 outlet on a 20 amp circu…it. 120 volts x 20 amps = 2400 2400 / 180 volts = 13.333 outlets I personally never put more than 12 on a 20 amp circuit.
