The electrical code allows outlets to be installed with the ground plug hole facing up, down or sideways. It’s up to you, there is no standard electric outlet orientation. So that means there really is no such thing as upside down outlets.
The National Electrical Code requires that you have an electrical outlet within 6 feet of the corner of the wall and at least 12 feet from the same wall.
Because if a cord or wire were to fall down on a partially plugged in right-side up outlet you would short out between the hot and the neutral. When the outlet is “upside down” in the above situation the wire would touch ground first.
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.
Typically an electrical receptacle is wired with two insulated wires and a bare ground wire, all three of which are encased in a plastic (NMC) or metal (BX) jacket.
In new homes, if you open up your outlet, you will usually see two wires. One entering and providing power to the outlet, the other exiting and providing power to outlets downstream. There may sometimes be a third wire to ground the outlet, or to provide power to a downstream line in another direction.
More Than Two Cables in the Box
The only appropriate way to wire a receptacle in a box with three cables is to use pigtails to connect the receptacles. Never connect more than one wire under a single screw terminal.
The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel. … This is to prevent the electricity from running through you!
Receptacles, unless listed as receptacle assemblies for countertop applications, shall not be installed in a face-up position in countertops or similar work surfaces.
In kitchens, all outlets that serve countertop surfaces should be equipped with GFCI outlet protection. That would include any outlets on walls, behind wet areas (sinks, etc.) that have features such as countertop breakfast bars (open counter surfaces above sinks used to sit at on the opposite side).
But there is a better way. By installing electrical outlets in the baseboard molding of your home they can seamlessly integrate into a design element that almost camouflages the outlet. By doing this small detail, you can eliminate the presence of noticeable unsightly cords and wires from your home.
The US National Electrical Code, Section 210.52, states that there should be an electrical outlet in every kitchen, bedroom, living room, family room, and any other room that has dedicated living space. They must be positioned at least every twelve feet measured along the floor line.
The neutral conductor is connected to earth ground at the point of supply, and equipment cases are connected to the neutral. The danger exists that a broken neutral connection will allow all the equipment cases to rise to a dangerous voltage if any leakage or insulation fault exists in any equipment.
Black (Hot) goes on the smaller prong side or white to silver screws, black to gold screws.
Set a multimeter to measure voltage. Insert a probe into each slot and read the line voltage measurement. A properly working outlet gives a reading of 110 to 120 volts. If there is no reading, check the wiring and the outlet.
