Is a 50-20 duplex main circuit breaker adequate for a three bedroom house with 13 outlets?
No! At this time I wouldn't have less than a 200 amp service for a 3 bedroom house. Keep in mind just because there is a place to plug "stuff" into doesn't mean there is enough capacity in the wiring to handle the load. Please call an electrician. The Fire Department call would be much more expensive.

for USA, Canada and countries running a 60 Hz power supply service. Circuit loading In North America 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. ( This is not found in the National Electrical Code) Generally each duplex outlet may count for 180VA. For a 15A circuit = 8 duplex max. For a 20A circuit = 10 max. This is in the Wiring Code, by the way. (This only applies to non-residential applications) In some states the 3 amp per outlet is still being used. For this case, 6 outlets max. ( What States?) In dwelling units there is no requirement for a maximum number of outlets on a circuit. The circuit could serve a single room of 500 sq. ft. and serve as many outlets you wanted including the lighting loads. (3 watts per sq. ft X 500 sq. ft.) This is the minimum requirement of the code and not necessarily good wiring practice. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself, on electrical circuits, equipment or appliances, always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB SAFELY AND COMPETENTLY REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Why would all three outlets in a bedroom and the bathroom light lose power even if the breaker is reset?
Answer Wires could be disconnected from the main fuse box. Check to see if you have any Ground Fault Outlets installed and ensure that all have been reset. It sounds li…ke they may all be on one circuit and if so, You need to check that all outlets nad light fixtures have good connections and are tight. Answer Its possible that you have a GFI outlet in bathroom that is tripped or is bad the bedroom outlets are possibly wired to same circuit Answer It just may be that the fault that tripped the breaker also broke the circuit to the other points. Look into the boxes of the outlets and switches. If there was a fault you may see carbon where an arc broke a wire to the remaining points in the string.
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 yo…u want to up your amps.
Could a bad circuit breaker light switch or plug outlet cause the bedroom light to flicker when turned on?
Answer Yes a bad circuit breaker and a bad light switch can cause a light to flicker when its turned on. It could also be caused by loose wiring going or c…oming from that paticular circuit. it also could be something in the fixture itself causing. Checking for loose connections is your cheapest and first route to go.
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.
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.
Put in a new one
Can an AC circuit breakers be used on a DC circuit and will this give that circuit adequate protection?
Check the nameplate on the actual breaker. Some breakers are rated for AC or DC. If it doesn't specifically list DC on the nameplate, then no, you should not rely on the break…er to adequately protect the circuit.
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.
In North America it is code regulations that a breaker or fused disconnect be installed between the utility supply and the customers distribution equipment. A main circuit bre…aker is a switch that is used to isolate the electrical utility supply from the customers service equipment. With this switch in place it allows maintenance to be preformed on the distribution panel in a de energized state. The sizing of the breaker is governed by the wire size feeding the distribution panel. In new homes today the standard size of distribution is 200 amps. In the 1940's this safety protection switch was not mandatory, which lead to great electrical damage to customers equipment if a fault occurred. Transformers are usually over fused on the primary up to 300 to 400% so that if an occasional tree limb crossed the line to ground , the limb will most likely burn off and the utility company wouldn't have to come out and replace the fuse that opened. Through calculations a 50 KVA transformer used for 200 amp services faulted line to line on the secondary there could be 12302 amps. The transformer primary, fused at 300 to 400 percent, could raise the amperage to 36906 to 49208 amps instaneous.
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.
Will my electrician need to run new wire from the outlet to the circuit breaker to change from a 50 amp to a 60 amp outlet?
Maybe not. Since there is no wire with a rating of 50 amps exactly there may be 60 amp wire already installed. Range's use a #8 wire with 50 amp range receptacle for its circu…it. If the wire that is installed now is # 6, that is good for 65 amps, then no wire needs to be changed. The only 60 amp receptacle that will be allowed on the 60 amp cable is a three pole four wire grounding 125/250 volt device. The number will be 14-60R. There is a three phase rated receptacle in the three pole four wire grounding type. It is a 15-60R.
no main circuit breker =circuit breaker
Technically, they can be on a 15 amp breaker when you use 15 amp outlets. There is a difference. Be sure to check your local code (just call the city building department and t…ell them you have a code question). some cities require the bedroom outlets to be on an arc-fault breaker.
Why would using a small kitchen appliance trip the circuit breaker for the bedrooms and not for the outlet that it is plugged into?
Kitchen outlets are rated at 20 amps and only dedicated for the kitchen. code states that there must be two 20 amp circuits supplying kitchen small appliances. bedroom outle…ts are fed by a 15 amp circuit most likely and that circuit is most likely feeding two rooms or so.
A circuit breaker sets a limit on the amount of amperage that can be applied to the circuit's conductor. This is why wires and breakers have amperage ratings. The wires ampaci…ty is matched to the breakers ampacity. If there is a higher that normal amperage capacity, than what the wire is rated for, the breaker will trip the circuit open.
