Is my house 110 or 220?
Most houses today have two 110 volt wires and one neutral wire running into the house from the local distribution system. These wires can run underground or above ground. If there are two 110 volt wires running to the house, then the house has 220 volt service and appliances, such as dryers and air conditioners.
What should my house voltage be?
Electric service providers supply 240 volts of electricity to your home, but this does not mean the voltage remains constant. The voltage can fluctuate between 210 and 250 volts from time to time, depending on how the loads flow through the provider's power stations and switching facilities.
What is household voltage in Canada?
120VIn Canada the supply voltage is 120V. If the appliance or its power supply are not dual voltage rated, the single voltage appliance will have to be used alongside a voltage transformer or converter to allow the appliance to work safely and properly (unless the appliance operates at 120V).

Are house outlets 15 or 20 amp?
Most homes in the U.S. are wired with a combination of 15-amp and 20-amp, 120-volt circuits. Because 15-amp receptacles can be used with 20-amp circuits, most of the outlets you see in American homes are the standard 15-amp variety, with two slots and a U-shaped grounding hole.
Is 127v too high?
It might be a good idea to find out just how high it is going above 127 VAC, but if it is only going above it slightly and briefly, probably not a problem. Yes, that's the key. If the system is simply reporting "over 127" then you don't really know yet how serious it is.

Types of Electrical Outlets and Receptacles
There are a various types of electrical outlets designed to match the requirements of your appliances, power tools and electronics.
Combination Outlet
Combination outlets provide two features in one device (ex: outlet with a light or a switch).
GFCI Outlets (Ground Fault Circuit Interrupter)
A GFCI outlet protects against dangerous ground faults, which occur when electrical current travels through any abnormal path to the ground.
AFCI Outlets (Arc Fault Receptacle)
An AFCI outlet protects against electrical fires resulting from arc faults by interrupting power, reducing the likelihood of a home’s electrical system being an ignition source of a fire.
Weather-Resistant Receptacle
Required by the 2008 National Electrical Code in damp or wet locations, such as patios, decks and pool areas, or any other residential outdoor location.
Rotating Outlet
Can be positioned to accommodate more than one large plug from cell phone chargers, hairdryers, cordless appliances, night lights and more.
Specialty Outlets
Many appliances, tools and electronics require specific types of electrical outlets to operate safely and at peak efficiency.
