240 volts. Using ohms law, at 240 volts, two 1300 watt hair dryers would draw a maximum of ~10.83 amps.

What Voltage type are in outlets at home?
Your home electrical wall outlets current capacity is governed by the breaker that feeds that circuit. In most home situations the wall receptacles are fed with a 15 amp breaker. Dedicated outlets could have a higher ampacity as they are installed for specific appliances or devices. To check your circuit, plug a lamp into the outlet. Start flipping the breakers off. When the lamp goes out that is the breaker for that circuit. Look on the handle of the breaker and it will tell you the capacity of that particular circuit.
Can you use a 20 amp circuit breaker for an electric dryer?
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 use 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.
Do hand dryers in a bathroom need a GFI breaker?
Make sure that all electrical outlets in the bathroom are grounded to prevent electrical shock. When in doubt, consult an electrician and have a GFCI (ground fault circuit interrupter) outlet installed.
Are circuit breakers inside clothes dryers?
Most dryers do not have internal circuit breakers, but they DO have "high temperature" sensors that shut down the heating element. Often motors will also have a shut-down feature that prevents internal damage.
Is it possible to simultaneously operate 1300 w hair dryers on the same 120v circuit without tripping 15 a circuit breaker?
Look on the data plate on the hairdryer. There you will find the manufacturers specifications as to the wattage of the dryer and the voltage range it has been designed to run on. So the answer is that a hairdryer can be plugged into a 120 volt receptacle if it was designed for use on that voltage. If you want to know the current it takes, you can calculate it by dividing the wattage by the voltage. The answer will be in amps. If the hairdryer is a type that was designed to run only on 230 volts - such as are made for home use in Europe and elsewhere,where they use that voltage as standard - then don't try to use it on 120 volts because you will not get enough heat from it!

How many volts do machines like welders or electric dryers take?
Most full size residential dryers and the majority of consumer-level welders run off of 220 volt single phase, residential type voltage. Only, with welders, you may need a higher amperage, dedicated circuit and breaker installed by an electrician, to properly operate it.
What size amp circuit breaker should be used for a gas dryer?
Typical residential electric dryers are on 30 amp circuits, which means 10 gage copper wire. The circuit breaker should match the dryer cord rating, generally 30 amps.
At what voltage should hair dryers be set?
The voltage for anything should match the supply voltage.
How do you upgrade the service from a 120V 100A circuit breaker to 240V 30A for appliances like ovens and dryers?
Have an electrician wire you a proper line for the appliance. You were just kidding about the 100A, right? 10, or 20amp, not 100.

Why are hair dryers not earthed?
Things that aren't grounded, like hair dryers, are double insulated. If the hair dryer gets a short circuit, the two layers of insulation will protect you. Hair dryers also have a ground-fault circuit interrupter plug that protects you if you drop the appliance in water.
What is the maximum number of amps allowed on a single circuit in your house?
Theoretically it is whatever the capacity of your main panel is and what the power company is providing. However, from a practical standpoint you typically use a 20A circuit for groups of outlets (8 to 10 per branch circuit) and 15A for lighting circuit. Then for special fixed appliances like refrigerators, stoves, washers, dryers and dishwashers you use a breaker rated for the appliance and it is the only device on the circuit. Things like HVAC, well pumps, electric heat will also have their dedicated circuits. In a typical house the largest breaker is likely in the 50 to 60 A range. If there are subpanels involved you could have a 100 A breaker in the main panel that protects a subpanel.
Do you have dryers in the US that work on a 110 circuit?
Yes.Another AnswerGas dryers typically use 120VAC and use natural gas or propane for the heat source.
