What's the difference between a polarized power cord and a non-polarized power cord?
An appliance with a polarized power cord has a NEMA 1-15P plug with prongs that match the outlet. It will only go in one way. An appliance with a nonpolarized power cord also has a NEMA 1-15P plug, but the prongs are identical, so it can go in either way.
Can you use a non-polarized power cord?
Modern power supplies like the one in your TV do not care or even notice how you connect live and neutral so it does not matter how you connect them. So you can safely use a non-polarized lead, the TV doesn't care at all assuming it is designed properly according to modern safety standards.
Can a non-polarized plug go into a polarized outlet?
All polarized and non-polarized plugs will fit into a polarized socket, but polarized plugs will not fit into a non-polarized socket. The need for one or the other is equipment specific—what is required within the equipment internal circuitry.
What does it mean if a power cord is polarized?
The system of hot and neutral wiring is what is meant when we speak of a house's electrical system as being "polarized." It simply means that there are both neutral and hot wires and that there is a directional flow to how the current runs through the system.
Does it matter which way you plug in a non polarized plug?
So although flipping the plug around and inserting it backwards will probably be no problem with regard to the electrical operation of the appliance, it may create a safety hazard by exposing the "hot" half of the outlet, the half not connected to Earth, such that someone might touch it and be shocked.

any cable that fits should work?" is, Yes. Here in the US, any non-polarized 18 AWG (7 Amps) 125V AC power cord should work. However, Microsoft and the Xbox team cannot make any recommendations other than using the AC power cord that came with your Xbox One S.
Can I replace a non-polarized plug with a polarized one?
replacing a functioning non-polarized plug with a polarized plug will not make it safer. However, the opposite (replacing a polarized plug with a non-polarized plug) could make a device unsafe to operate.
How do you wire a non-polarized plug?
If the plug is polarized, put the hook of the neutral wire over the silver screw in the plug, with the hook going clockwise around the screw.

What is a polarized plug used for?
Polarized receptacles are electrical outlets that have two slots: a small "hot" slot and a larger neutral slot. Polarized receptacles ensure that the electrical currents flow along the appropriate wires in the circuit; hot along hot, neutral along neutral.
What is a non polarized plug?
Non-Polarized plug. Plugs with the two of the same-sized prongs are considered non-polarized because there is no clear distinction as to which prong is for the “hot” side and the “neutral” side.
How to tell if an outlet is polarized?
The simplest way to tell if your receptacle (electrical outlet) is polarized is if you are able to plug in a three-prong plug (NEMA 1-15 ground Type B) or if a two prong-plug (NEMA 1-15 ungrounded Type A) can only fit with the larger prong on the left. An electrical plug is designed to complete an electrical circuit from your home’s electrical ...
What is a three prong wire?
The grounded wire (round prong), in a three-prong design are used as an extra safety precaution for electrical devices like a microwaves or coffee pots.
What is an electrical plug?
An electrical plug is designed to complete an electrical circuit from your home’s electrical panel to your electronic device and back. The hot, neutral, and ground wires are intended to complete the electrical circuit in a specific way as shown below.
What is the difference between hot wire and neutral wire?
Hot Wire: (Black wire) provides a path of 120 VAC (volts alternating current) electrical devices require to operate. Neutral: (White wire) provides a return path for the current to electrical panel and is usually connected to an earth ground.
Do receptacles have polarized wires?
Thankfully, most receptacles in US homes today are polarized. For newer electronic devices, even though the two-prong design doesn’t feature a grounded wire, most non-polarized plugs are double-insulated as a safety precaution. That means that there are two layers of insulation between any live wires and any metal parts within ...
Why are most appliance plugs polarized?
But it provides a measure of safety for the appliance and house wiring to be aligned in terms of polarity. This is the reason why most appliance plugs are polarized—so they can only be plugged in neutral-to-neutral, hot-to-hot.
What does it mean when an outlet is unpolarized?
This too is sometimes seen in older homes. When you find an outlet that has vertical slots exactly the same width, it means you are probably looking at wiring that is quite old. These unpolarized outlets can be very inconvenient since polarized plugs will not even fit into them.

Can you use an unpolarized plug on an old lamp?
It is entirely likely that you have some appliances or other devices around your house in which the plugs have blades of equal width—nothing to distinguish neutral from hot. These are unpolarized plugs. Older lamps and other devices may well have unpolarized plugs, and some modern electronic devices, such as chargers on computers or cell phones, also have simple unpolarized plugs. It is generally not a problem to plug in an unpolarized plug to a polarized outlet in whatever way it will fit. But anytime you are replacing a plug on an older lamp or appliance, it's a good idea to install a new polarized plug.
What is polarized wire?

What is the difference between polarized and non-polarized sunglasses?
What's the difference between polarized and non-polarized sunglasses? Polarized vs. non-polarized sunglasses both darken a bright day, but that’s where their similarities end. Polarized lenses can reduce glare, lessen reflections and make daytime driving safer; they also have a few drawbacks.
Why do people wear polarized sunglasses?
Polarized sunglasses can be a lifesaver during sunny daytime driving, especially when sunlight hits at just the right angle to interfere with your vision. Polarized lenses filter the sunlight that reflects off roads, snow and windshields, neutralizing most or all of it. The result is a safer driving experience, free from the distraction and discomfort of glare.
Why are polarized sunglasses anti-reflective?
The special coating in polarized lenses is highly anti-reflective, working around the clock to reduce reflections, haze and glare. At the right angle, looking at a lake or ocean through polarized sunglasses will allow you to see past most surface reflections and through to the water below.
Can polarized lenses cause darkness?
For example, screens viewed through polarized lenses can appear slightly faded or, in some cases, completely dark, depending on the angle from which you’re viewing the screen. While this usually only happens when the screens are rotated at an unusual angle, it’s worth noting that non-polarized sunglasses don’t cause this visual distortion.
