Will a 240V solid state relay work with 120V?
No. If you are looking of a relay that will allow 240V, many suppliers sell a SSR that will handle up to 280V AC. Most are triggered by 3-32v dc. Just google: solid state relay OR solid state contactor Read More
You are building a new house and trying to decide between 120v and 240v which is better More practical?
In the US, both 120v and 240v will be needed for your home, as different appliances need different voltages. Your TV needs 120V, while your electric dryer and stove will need a 120V/240V supply. If you have an electric water heater, or central AC unit, they will need a 240V supply. Read More
No. The neon sign is fed by a step-up transformer. Primary side 120V, secondary side 7500V. If you applied 240 to the primary side you would get 15000 volts on the neon tube. A flash over and then nothing. If you can find a transformer from 120V to 240V or 240V to 120V then you are good to go. Connect 240V to 240V side and you will get 120V out the other, connect the 120V… Read More
Because they are "in-phase". In order to get 240v, you need two 120v Alternating Current lines that are 180° out of phase, that is, opposite phases. Only when one line is +120v and the other -120v will you see 240v between the wires. Read More
You cannot use 2-120v outlets to power a 240v dryer. You can convert a 240v dryer outlet to power 2-120v outlets if they are supplied with a neutral. This requires a competent electrician. Do not do this yourself. Read More
120v or 240v. 120v is one leg of the main panel, and 240 is two legs of the main panel. 120v is lights,outlets. 240v, dryer,stove. Read More

120v and 240v Read More
Generally 220v anything works easier or with less effort so can be cheaper to run. Appliances that run off 240V draw less current than 120V appliances so lighter wiring and fixtures can be used. However, 240V is more prone to arcing than 120V. Also, 240V is more likely to blow you away than 120V, whereas 120V is more likely to "grab" (Cause your muscles to involuntarily contract, i.e. making your hand grab a conductor) you… Read More
How do you hook the 4 wires which are 2 whites 1 red and 1 black coming from the back of a generator to an outlet for 120v and 240v?
The whites are Neutrals or Grounds and the Red and Black are each 120v. One white and either the black or red for 120v and one white, both the red and black for 240v. Read More

How do you change a double pole 240v breaker to a single pole 120v breaker to allow a regular 120v receptacle to work?

240 refers to the voltage used in an electrical system. The US uses 120V/240V, while the UK uses just 240V. Read More
You can using a transformer, but you won't have as many amps available. 5000 watt generator @ 120v = 41.66 amps 5000 watts / 240v = 20.83 amps Read More
You have three feed wires on US residential service: 2 hots and neutral. These wires are connected to a 240V center tapped transformer with the neutral connected to the center tap. So, you have 120V between either hot and neutral and 240V between the hots. There is no neutral in this circuit because the load doesn't require 120V, it draws 240V directly from both hots. Read More
it won't work properly Read More
Absoluteyl not. Read More
I assume its 120V already: so, yes, you'll have to wire for a 240V receptacle (240V uses 1 more current carrying wire than 120V). Even if there were enough wires at 120V you'd still need a larger size wire for the combo unit. An electric dryer is a beast with electrical current. Read More
On a pure 240V circuit, no. There is no neutral. On a 240/120V circuit, yes. You have the needed neutral. Tapping 120volts off an existing 240volt branch circuit with a neutral is possible but is not a proper method. It does not comply with most electrical codes. Read More

How can you get 240V single-phase power from a 240V 3-phase service Can you just connect to two poles of the 240V 3-phase service?
If the 240V 3-phase service is 240V phase-to-phase, then you can get 240V single-phase by simply picking two phases (poles, as used in the question) and connecting the load across them. This is simply one third of a standard delta connection. If you need 120V/240V split phase, i.e. with a neutral, as used in residential services, you will need a transformer. If the service is actually a four wire "quadraplex" service, however, you will probably… Read More

It depends on the voltage source. watts = voltage * voltage / resistance and amps = voltage / resistance example 1: To produce 600W from a 120V source, you need a resistor of size 120V*120V/600W = 24 Ohm. This would pull 120V/24 Ohm = 5 amps. example 2: To produce 600W from a 240V source, you need a resistor of size 240V*240V/600W = 96 Ohm. This would pull 240V/96 Ohm = 2.5 amps. Read More
If you put a 240V bulb in a 120V lamp that has no transformer and plug it into a 240V outlet will it work or blow the circuitry?
Not only will it work, but it will last for much longer than if it was connected to 220volts! Read More
No, you must break it down to a 120 volt supply. Read More
What is the voltage? 120V the right blade with the blades facing you. 240V both. Read More
Yes, but you will only get one quarter of the wattage from the heater. Read More
the simplest solution is by connecting two 120v 3amps heater in series , the same can be used directly on 240v. However the current drawn will still be 3 amps & Not 1.5 amps. The heater output power will be double that of a single heater running on 120v. ( or equvalent to two heaters operating on 120v. supply ) A more expensive method is to use a stepdown transformer which can be powered on… Read More
120v and 240v cords usually have different end configurations and will not plug into the different recepticles. However, if you changed the plug end, and the cord has the proper size rating, then yes, you could use the same cord. But, it also depends on the cord too. Most 120v cords only have three wires in them. One "hot one "neutral" and one "ground" wire. A 240v cord would have FOUR wires, two "hot" wires… Read More
I think the only sure way is to put a high-impedance volt meter and measure the voltage across live and neutral. Don't forget that it's AC. You could look at the bulbs in the lighting to see if the say 120v or 240v. Read More
You have to replace the wire (as you are increasing the current capacity), the outlet, and the breaker. Essentially you have to remove the old circuit and put in a new one. You can't reuse parts of the old circuit as you are increasing the current capacity and they would be underrated. Read More
It depends on the voltage source in question. watts = volts * volts / resistance and amps = volts / resistance example 1: Producing 7kW from a 120V source will require a resistor of size: 120V*120V/7000W = 2.05 Ohm And this will pull 120V/2.05Ohm = 58.3 Amps of current. example 2: Producing 7kW from a 240V source will require a resistor of size: 240V*240V/7000W = 8.23 Ohm And this will pull 240V/8.23Ohm = 29.2 Amps… Read More
More than likely, your 240V system has branches that supply a standard household 120V to things like lighting outlets. Most light bulbs in the US run on 120V so this is probably a convenience feature. Otherwise you would have to go to a specialty store and buy 240V bulbs. Read More
