I guess at the end of the day, the only thing that matters is that the socket allows the circuit to be closed. An appliance doesnt know the difference between which direction the current is flowing through the outlet. Its as if the outlet was installed upside down.
What happens if you hook up an outlet backwards?
In a correctly wired outlet, electricity will flow to the switch; with reversed polarity, it will be present in the item itself even when it is not turned on. In either case, the item will not function until the switch is flipped to close the circuit.
Which way should an outlet be installed?
The outlet should be oriented with the ground pin down because a person grabbing the outlet will have their index finger at the bottom side of the plug and the index finger sticks out further than the thumb. Having the ground down will keep a persons index finger from touching the live pins.
Why are some electrical outlets installed upside down?
Electricians may position the outlet in an upside-down position so that you can quickly identify the switch-controlled receptacle. Since it stands out visually to most people right away – it provides convenience to the occupants to easily remember which outlet is switch controlled.
Will an outlet work if wired backwards?
Most electrical outlets (properly called receptacles) today are grounded three-prong outlets. But heres the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward.
How can you tell if a wall outlet is bad?

How high off the floor should an electrical outlet be?
about 12 inches Standard Height for Outlet Boxes The standard height for wall outlet boxes is about 12 inches from the top of the floor covering to the bottom of the receptacle box (or 16 inches to the top of the box).
Is it code to install outlets upside down?
The electrical code allows outlets to be installed with the ground plug hole facing up, down or sideways. Its up to you, there is no standard electric outlet orientation. So that means there really is no such thing as upside down outlets.
Will reverse polarity trip a breaker?
Reverse polarity will not trip a breaker. Only a dead short will. Pull the receptacle out and give us clear pictures of all the wires and connections. It sounds as if you have connected the grounded neutral conductor on that circuit to the hot wire, probably at the receptacle terminals.
Can reverse polarity damage speakers?
The answer is no, thankfully. The voltages being applied to a speaker with inverted polarity are no different from those supplied to a speaker with correct polarity. Your equipment will not be damaged. The worst thing that will happen is that it will not work well acoustically with properly wired speakers.
Can a bad outlet cause an open ground?
This is unsafe because an appliance that is designed to use an equipment ground to discharge an unsafe fault condition will not have a conductor to discharge that fault. When old two-prong receptacles are replaced with modern three-prong receptacles and a grounding conductor is not added, you create an open ground.
Why would an outlet have power but not work?
There can be a number of reasons a receptacle stops working. The problem could be as simple as a loose connection; the wires could also be damaged, which might require a brand new circuit. A device might still be working, but could have serious—and potentially dangerous—underlying issues.
Why would an outlet work intermittently?
Any time there are outlets that intermittently dont work, it is cause for concern. A loose connection can not only cause an intermittent interruption of the power supply, but will tend to overheat and can pose a fire hazard. In my experience, apartments in old houses often have marginal-to-inadequate power supplies.
What is code for electrical outlets in a basement?
Standard basement electrical outlet height is 15” as per the NEC – National Electrical Code. This measurement is taken from the bottom of the receptacle box to the level of the floor below. There are no special guidelines for basement outlet height as per the NEC – they are the same height as any other floor.
How many outlets can you have on one circuit?
National Electrical Code & Outlets The National Electrical Code (NEC) does not limit the number of outlets per circuit. The NEC only states that a circuit cannot supply more than 80% of the circuit breakers limits. This is so the circuit breaker does not constantly trip during regular use.
How many electrical outlets can be on one circuit?
There is a maximum of 12 outlets connected to a circuit.
