When using a copper split bolt connector on 120V wire what is the best way to protect it when it needs to be waterproof and underground?
Split bolt connectors are a mechanical connection and are not approved for underground splices. Use an approved C clamp or butt splice hypress connection for the splice. Install heat shrink over the wire before making the splice, to seal the connection for underground waterproofing.
Are 120V and 208V the same?
no 208v is bigger
Why are you not getting 240v between the two hot wires?
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.
How do you get 120v from 220v socket?
You don't, at least, not legally.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,

Can an overhead 400W light with built in ballast that is currently wired to use 480V be rewired to use 120V?
Only if the ballast is a multi tap ballast.:Even if you could install a 120V ballast, or tap it to 120V with the existing one, Current may become an issue. To run the 400W light (sodium?) Now instead of the .833 amp range it's more like 3.33 amps. Supply wiring would have to be able to handle that. Those types of lights are often on long runs to building and grounds lights, parking lots, etc. Using 480 saves a lot on wiring costs.
Can you change electricity from 120V to 240V in your kitchen so that you could use a new electric oven instead of an old gas oven?
No The wiring isn't big enough to carry the load of an electric range Christmas is no time for a fire! Call an electrician!
Can you convert a 30 amp 120V RV receptacle into a normal 120V outlet?
You can, but your circuit will be "protected" by a 30 amp breaker. So you'll have to consider the safety issues of having wiring and appliances that can draw up to 30 amps before tripping the breaker. Will the wiring and circuity support that much current without damage? If not, then switch to a 15 or 20 amp breaker.
What is the output on this exhaust fan?
This fan is rated at 277 CFM using 120V of power.
How many amps does 230 watts equal is you are using 120V ac circuit?
1.9 amps
Which wires go where when putting a power cord on a 120V compressor motor?
In common house wiring, black is the power wire, white is the neutral, and green is the ground wire.
Why will a light not work on knob and tube wiring with 120V of power on meter?
According to www.wilberelectrical.com knob and tube wiring is no longer legal. You will need to replace it. Chances are, as knob and tube wiring is very, very old, something has broken or it has been disconnected as knob and tube is not very safe. I would recomment replacing it with modern wiring devices rather than trying to repair it.
Do any Dehumidifiers run on batteries?
Due to the power required,you will need to runa dehumidifier using 120V power.
If you purchase a chandelier in the US that is made for 120V houses does it need to be rewired for 220v in order to be used in Italy?
You cannot use them on 220 volts the bulb are for 110 volts.The wiring is ok.
How do you wire 240V to 120V?
What specifically are you wiring? A light bulb would operate dim, a motor will burn up. The current increases thereby requiring larger wire and current protection.
Why insulation resistance test is required?
every insulator has its own voltage range depending on its intended use. we test insulation for the required operating voltage range. usa uses a document known as nfpa 7 or nec most common residential wiring 120v to ground is in the 300V class the specified test voltage for 300V wire and wiring devices is 2 times the working voltage +1000v which is 120v x 2 + 1000v = 1240V spec 1600V for industrial wiring its 600V class wire and wiring devices 480V x 2 +1000v = 1960V spec 2200V for most uses a 2500 volt megger is sufficient
