![]() Mostly used electrical outlets in houses are 110 volts. it may cause overvoltage which might result in electronic fires or blasts due to heavy access to power than its standard. If you connect a 220v over 110v outlet, it might cause the connected gadget to act weirdly or get damaged as most electronic devices can’t endure 50% under voltage. It’s a bad idea according to most experts. It is possible to wire a 220-volt outlet with 3 wires as well. By contrast, a 220-volt circuit connects to both bus bars, so two breakers are needed – one for each bus bar and each wire that connects to that bar.Ī 220-volt breaker is known as a double-pole breaker, and it consists of two 110-volt breakers bonded together. The terminal screws in 220V plugs and outlets are accordingly larger.Įach 110-volt circuit connects to a single bus bar and has only one hot wire, so only one circuit breaker is needed. Whereas the normal maximum wire size in a 110-volt circuit is 12 gauge. Because 220-volt circuits carry higher current, they require 10 gauge or larger wire. A 110V outlet (and plug) has only one hot terminal, and the hot wire is always black.Īnother key difference between 110 and 220 circuits is the wire size. That means a 220V plug has to have an extra hot terminal, which is brass by conventionĪlso by convention, the hot wires are colored black and red. If you look at a 220V to 110V wiring diagram, you’ll note that a 220V circuit has two hot wires. What’s Inside a 110-Volt or 220-Volt Outlet? ![]() By that law, you can easily dictate that a 110-volt outlet possesses a lower risk of electrocution.Īnd based on the same rule, we can determine that a 220-volt outlet has a greater risk of electrocution. The lower the voltage, the lower the risk of electrocution. This could affect your decision if you have a shortage of space. Outlet SizeĪ 10-volt outlet is visually smaller when compared to a 220-volt outlet. ![]() Installing a GFCI outlet with 4 wires is quite easy. But in a 220-volt outlet, the socket might be 3-pronged or 4-pronged. In a 110-volt outlet, the sockets are 3-pronged. If the number of prongs doesn’t match between your device and the outlet, then it may become difficult for you to use that outlet, even if it matches the device in other areas. The discussion of prongs is also necessary. But on the other hand, a 220-volt power supply outlet requires a thinner wire. Lower voltages as such as 110-volt usually require a thicker gauge. Effectiveness in GenerationĪ 110-volt outlet or 50Hz power is comparatively less effective in the generation of electricity.īut 60 Hz or 220-volt is more efficient in both the generation and transmission of power or electricity in general. 60Hz systems tend to use more voltage for the domestic power supply than 50Hz. Frequencyįrequency is also another important factor to consider when choosing an outlet.Ī 110-volt outlet runs on a 50 Hz power supply whereas a 220-volt outlet runs on 60 Hz. Otherwise, if it requires a 220-volt power supply, go for a 220-volt outlet. If your device requires a 110-volt power supply, you should use a 110v outlet. It also dictates how many watts the outlet can handle. The voltage is the first difference between these two outlets. Factors to Consider when Choosing the Appropriate Voltage Voltage A further brief on the topic is provided below. The necessity of the voltage depends on the task. The answer to this question depends on you and your specific use case.
