# Can 115 volt appliances work safely with 120 volt wall outlets? Will they fry from a slightly smaller voltage?

An appliance has a "nominal voltage" which might be specified as 115V, but to legally sell such a product requires that it operate over a range of voltage, typically about 20%.

US wall outlets can run from 110 to 130 volts in some cases. Appliances are generally made to tolerate any voltage in that range. Computer equipment with a switching supply will often tolerate an even wider range of voltage. We didn't advertise it as a spec, but the computers made at my former company were tested to work between 95 and 260 volts.

The manufacturer of the appliance.

The manufacturer of the wall outlet.

The manufacturer of the electricity.

Will they fry from a slightly HIGHER voltage?

No.

Yep will work fine. The standard is from 110 to 125 volts.

SURE IT IS SAFE TO USE WITH 5 VOLTS DIFFERENCE.

They work safely. 5 volts come in the error bar. Say 115 Volts draw 2 Amp current. Its resistance is 115/2. In the presence of 120 volts, it will draw

120*2/115= 48/23= 2.08 A approximately. I think this will be ok.

resistive loads work fine,albeit low output
