The rating of switches depends on multiple factors i. There are two main rating for a switch:. All the switches, breakers, plugs, outlets, connectors and wires etc having two amperage rating. Safe maximum: switches, plugs, breakers, connectors, wires etc have a safe max amps.
The maximum current rating depends on the circuit voltage and should never exceed the exact current rating. If it exceeds, it will melt and weld the switch contacts and the switch will be useless. If there is no breaker, it may lead to damage the connected device even cause a dangerous fire.
In simple words, A 15A switch should not be used for 20A load current. Mostly, 30A 10 gauge circuits are used for V AC supply according the load wattage i. Most residential devices are 15A, but on occasion a 20A device may be appropriate. Related Switch Wiring Tutorials:. Example: What is the safe maximum current in amperes of a 15A switch? It means, a 15A switch can be used safely for a 12A load current.
Although, the 15A swicth can be used for exact 15A switch for non-continuous non-simultaneous load. While in case of continuous load, a 15A switch should be used for maximum of 12A load circuit. Voltage rating of a switch shows the maximum allowable voltage of the circuit where the switch has to be used for different loads.
A switch can be rated for AC voltageDC voltage or both having different values and ampacity. Read the user manual or nameplate data on the switch before installation. The supply voltage should never exceed the voltage rating of switch.

In other words, If we connect an V switch on V, the applied voltage may jump over the open contacts and overheat due to overvoltage of the circuit and connect the load to the supply voltage. It will lead to spark as well which may cause fire.
It only takes a minute to sign up. OK, the one answer I got was way off target, and another commenter couldn't figure out what I was asking, so I'm restating the question Are 15A 3-prong grounded outlets actually rated to 20A, allowing them to be used on 20A circuits? And if so, why, when the outlet can never be asked to supply more than 15A by anything that would be plugged into it?
This question had a comment that 15A outlets were actually rated to 20A. However, by design, there is nothing that will plug into a 15A outlet that will draw more than 15A. An appliance that draws more than 15 amps would have a "T-blade" plug that wouldn't go into a standard 15A outlet. In addition, outlets are always wired in parallel, meaning that a 15A outlet would never have to transmit the amperage draw of a "downstream" outlet; you never "daisy-chain" outlets by connecting hot to neutral, for a number of reasons.
A 15A outlet is rated for 15A, with a 20A pass through. That is to say that the 20A circuit is in continuance throughout the circuit, however the receptacle itself the contacts are rated for 15A continuosly.
The total circuit draw multiple appliances - same circuit can be 20A before the breaker trips. A 20A breaker used with 12awg wire can feed multiple 15A outlets, one example is the kitchen. The reasoning is so that today's demanding appliances, which draw more current, can be used with a 20A breaker without the worry of nuisance tripping. If more than a total of 20A were to be drawn from the circuit, the breaker will trip. If it were to short, it will trip the 20A breaker just as it would a 15A breaker.
A 15A receptacle can take 20A for a short time with no problem. The receptacle is overrated, otherwise it would blow up upon a short.
A short circuit in actuality can be hundreds of amps in a very short duration. The breaker and receptacle are rated as "Time overcurrent" meaning it can take a lot of current for extremely short durations, and will trip on lesser currents that occur for a longer time. An example one can relate to refer to chart : Joe plugs in two electric heaters in his family room.
Everything works fine until seconds later the breaker trips! Joe overloaded his 20A circuit, by drawing 40A!According to NEC, an outlet is the point s in an electrical wiring system where current can be taken and utilize by electrical appliances and equipment by plugging them in it. An outlet receptacle where one or more receptacle are installed or a supply contact device installed at the outlet to connect an electrical load through plugs and switches.
Ordinary outlet or standard outlet has screws terminals on both sides. The brass screws should be connected to the line hot, live or phase wire while the silver screws should be connected to the Neutral wire. In other words, the hot wire from main breaker should be connected to the narrow blade terminal where the Neutral wire should be connected to the wide blade terminal.
The ground wire is connected to the ground terminal mostly green color screw. Keep in mind that the brass screws for hot terminals are electrically bounded to each other by a break way fin tab hence, connecting one brass screw to hot wire will feed the power to the second brass screw as well. In some case, you may remove the breakaway fin tab between the two brass screws for hot wire and split the outlet for other specific application we will show in following wiring diagrams.
In today wiring tutorials, we will be showing that how to wire and install an electrical outlet in different ways. In this simple wiring diagram, multiple outlets have been connected in parallel. Each outlet is independent of each others as they are wired to separate cables. The following wiring diagrams show that multiple outlets are wired to a single pole SPST switch, one-way or two way in US switch. In this wiring, a switch is added to to an existing outlet by removing the hot wire from outlet brass terminal and connected to the first terminal of switch.
The second terminal of switch then connected back to the brass terminal of outlet. In this wiring, a light switch has been added to the existing outlet. The hot terminal of outlet is connected to the first terminal of switch and the second terminal of switch is connected to the lighting point.
Finally, the neutral wire from outlet is connected to the light bulb. In this wiring, the outlet operation has been split into two parts i. To do this, simply remove the breakaway fin tab between the brass terminals hot as shown in fig. Connected the switch output hot to the upper brass terminal and the lower hot terminal should be connected to the switch input hot wire.
In simple words, a common hot wire should be connected to the first terminal of switch and lower hot terminal of outlet. The second terminal of switch as hot should be connected to the upper hot terminal of outlet.
Finally, connect the neutral and ground wire accordingly as shown in fig below. In this wiring, the first and 3rd outlet hot terminals are connected to the Line 2 Blue and the second and last outlets hot terminals are connected to the Line 1 Red.
The neutral is connected from the main breaker to all outlets neutral terminal. Ground wire is connected to the outlets as well as shown in the fig. This way, all the dual outlets are connected to the single line of V and can supply V to the appliances. In this special wiring, a dual outlet is connected to both V and V where the upper portion provides V and the lower outlet provides V supply voltage.
