Can an appliance rated for 15A be operated safely on a 20A circuit?
Yes, as long as the circuit is not overloaded. Some kitchen appliances require a dedicated circuit depending on your local code. In my area the following require a dedicated circuit. Dish washer, refrigerator, microwave, garbage disposal, stove, and 2 separate dedicated circuits for all the rest of the kitchen receptacles. Check you local code.

What are the electrical requirements and how do you convert a 15A circuit breaker to a 20A circuit breaker?
Answer . Please be more specific....simply replacing the breaker with a 20 amp may cause a fire; if the cable is sized for 15 amp and is overloaded.. Answer . \nYour 15… amp breaker is probably feeding #14 wire. The use of a 20 amp breaker requires at least a #12 wire be used. Fire hazard if breakers and wiring are not sized correctly.
If the hot water heater and dryer are both run off of split 15A breakers is it safe to upgrade to 20A breakers?
You live in a mobile home, or older house? I live in a doublewide, and my dryer breakers are 30amp, and the water heater breakers are 20, both 220V lines, shared. The only saf…e way to answer this is to have an electrician look at your setup and determine if your wiring is capable for allowing a larger (bridge) to be installed. If they are tripping on a regular basis, it may be because you installed a new water heater that requires more current than what the breaker can handle, or a new dryer. The data labels that come with these units/appliances list the energy requirements needed to operate them. But an electrician will be able to tell you for sure. 15 amp breakers are usually feeding #14 wire. 20 amp breakers requires at least #12 wire.
No. You need 20 amp receptacles. ( if a single receptacle on an individual brach circuit NEC 210.21 (B)(1) ) Yes you can use a 15 amp receptacles on a 20 amp breaker in the s…tates but not in canada. ( branch circuit supplying two or more receptacle NEC 210.21(B)(3) ) 15 amp receptacle on a 20 amp circuit is not code, partly because 20 amp circuits use #10 ga wire, which does not fit unto a 15 amp receptacle,(can be forced but lots of work.) Also a 15 amp receptacle will not take the 18 amps continuios that a 20 amp recep. will. ( It is code, see above. 14 awg = 15 amp, 12 awg = 20 amp, 10 awg = 30 amp ) 20 amp wire is 12 gauge not 10 Yes you can use 15A outlets and swithes on 20 amp breakers they are UL listed for 20 amp even if they are stamped for 15A as long as the wire is 12ga to. ( NEC Table 210.21 (B)(3) )
Can you use 15A outlets on a 20A circuit with 12-2 wire and a 20A breaker and how many outlets would this allow?
I'm going to assume you are referring to residential construction because rules for commercial and industrial settings can be different. Also rules differ by geography (i.e. C…anada specifies a maximum of 8 outlets on a 15 amp circuit, USA code is silent on the issue but for practical purposes, more than about 10 will likely lead to poor performance. Some code also specifies max loading of a 20 amp circuit at 80% making 10 outlets the practical limit if using 20 amp outlets on that circuit. To expand on the previous answer a little, there is a large margin of safety in the construction of these components but if you think about it, you are placing a component that is rated at 15 amps into a 20 amp circuit. That outlet is potentially the weakest link in the circuit and could act like a fuse. If any of those 15 amp outlets are overloaded, it might overheat and fail before the circuit breaker. This is a recipe for a fire. You may think now that you'll remember to only plug in light loads, but these things have a habit of growing. You can plug typical small home appliances (lamp, stereo, TV, etc.) into a 20 amp outlet so the only benefit in using the 15 amp outlet is the minor cost savings at installation. If it were my building, I wouldn't risk it. If I can't talk you out of doing this and it's allowed by your applicable code, make sure you don't daisy-chain the circuit through the outlets. (In other words, don't run your 12-2 wire in one side of the outlet and out the other side.) Instead, use a pigtail (short piece of wire) to tap off your line to each individual outlet. . In the United States you can run 20 amp breakers with 15 amp outlets but not in Canada. And for how many? About 10 to be on safe side as long as they are all low amp usage appliances. TVs, steros, fans, lamps. You can run 20 amp breaker with 12-2 wire as long as you make sure you use the 12-2 wire that is rated at 20 amp. Whilst this was not your exact question it is worth saying IT IS NEVER SAFE to run a 20 amp load through a 15 amp receptacle. It is only rated to handle up to 15 amps. 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.

Can you use a light timer that is rated at 15A and 115V with a circuit that is rated at 20A and 120V?
Yes you can. Please be aware you have the situation of pulling more amps, in this case 5 amps, over the timmer before the fuse blows. which may damage the timer To avopid this… appliances plugged into the timer should be rated at 15 amps or less. Thgere are different type circuit breaker immediate and time delay for where an appliance such as motors exceed the limit to start then drop down when running?

What are the examples of household electric appliances under the heading of 5A and 15A current rating?
5A: lights, radios, televisions, tuners/amps, 15A: convector heaters, irons, toasters, microwaves.
A small appliance circuit will be protected by a circuit breaker rated at 15 amps if the circuit wires are #14. If the circuit wires are #12 then a 20 amp circuit breaker coul…d be used.
Safe? Yes. The only probles are: 1. it's a waste of 12 ga wire. 2. The next person to come along may see the 12 ga wire and think it's okay to put in a 20 Amp breaker.
The purpose of a fuse or breaker is to prevent electrical fires. Using a 30 in place of a 20 is not advisable even if it does not immediately cause a short. Taking a chance wi…th that is like playing with your life. Fuses are sized to protect conductors If the appliances plugged-in or connected to a circuit all used to work ok without blowing the circuit's 20 amps fuse, the first thing you must do is find out if a new fault has developed inside one of the appliances. A fault in an appliance is what needs to be fixed first and then you can repair or replace the blown 20 amp fuse with another 20 amp fuse. If the 20 amp fuse for a circuit blew because you have just plugged-in a different appliance that had not been used on that circuit before, it must be overloading the circuit and you should either : . plug the appliance into a separate circuit which can take the load without blowing its fuse or . re-distribute all the existing loads on the circuit until its 20 amp fuse stops blowing or . install an additional circuit with the right wire size and fuse or circuit breaker to supply all the required appliance(s) safely. Changing from an existing 20 amp fuse to a 30 amp fuse because the load you are trying to supply makes the 20 amp fuse blow would never be advisable - it is called "over-fusing". Before you ever do that you must be sure that the circuit's wiring is adequately sized for that higher current level. If there is a 20 amp fuse already, it is probably because the wire is only rated to carry 20 amps. Putting-in a higher fuse size would allow the circuit to be overloaded, with possible conductor damage and fire as a result House fires often break out because someone has put in a fuse with too high a rating and let it run continuously in an overloaded state. If left like that, it can eventually get hot enough to start a fire. 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.

What effect can be experienced by placing a 15a fuse in a slot rated for 5a on an electrical circuit?
For a circuit that is operating normally, it will continue to operate normally. However, by replacing the correct fuse with one of a higher rating, you are removing the circui…t's overcurrent protection and, in the event of a fault, the conductors and load may become damaged. Incidentally, the symbol for ampere is 'A', not 'a'.
yes, but make sure what it is switching is only rated to 15 A. Also, you can't do it the other way, unless, again, the final product that is being switched is only the 15 A … You can control a 15 amp load with a 100 amp switch, but not the other way around.
Yes, you can go down in current protection, but not up. With 15 Amps you just won't have as much capacity to power connected devices. If that isn't a problem you can make the …replacement, but turn off the power supplying the GFCI first.
Can you use 15A outlets on a 20A circuit with 12 2 wire and a 20A breaker and how many outlets would this allow?
It depends on if you have a single outlet (receptacle) on a branch or multiple receptacles on a branch. One receptacle on a 20A branch: The receptacle must be rated 20A T…wo or more receptacles on a 20A branch: The receptacles can be 15A or 20A Technical Reference: 2011 NEC 210.21(B)(1)A single receptacle installed on an individual branch circuit shall have an ampere rating not less that that of the branch circuit . 210.21(B)(3) Where connected to a branch circuit supplying two or more receptacles or outlets, receptacle ratings shall conform to the values listed in Table 210.21(B)(3), or, where rated higher than 50 amperes, the receptacle rating shall not be less than the branch circuit rating. Table 210.21(B)(3) 20A Circuit Rating 15A or 20A Receptacle Rating
It cannot be simplified any further, so it is: 5aÂ³ + 15aÂ² + 20a
Yes, it will be protected by a circuit breaker or fuse. The normalrating of the circuit breaker or fuse is 25% more than the maximumcurrent expected, or the maximum current al…lowed for the cablesize, whichever is lower.
