Can you run a 110v heater on 220v circuit?
No.It'll overload and fail just about immediately.It's possible - but not recommended - to run two 110 v heaters in series from a 220v circuit.
What is the impedance of a single phase inductive circuit having a voltage of 240volts and a current flow of 10amps?
Work it out for yourself. The equation is: Z = E/I, where Z is the impedance, E is the supply voltage, and I is the load current.
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.
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,,
The electrical resistance of a 100w 240v bulb will be?
42 ohm
Can you run two laundry dryers on one 220 circuit?
No you can only have one dryer on a 240v circuit and nothing else can be attached to it either considering your using a 240v electric dryer
You have 120v photo flash lights - how do you use them with 240v in Oz?
Power adaptors are readily available that plug into Australia's 240v outlets, converting to 120v. Find them in travel, luggage and electronics stores.
Can GFCI circuit breaker handle a 240V circuit with a 120V circuit sub-paneled off if it?
I don't know if you are trying to ask if you can run a 240V panel off a GFCI or run a 120 V sub panel off of a GFCI. Can you clarify please,,,Thanks
Would a 30A 240V circuit breaker be too large to safely support a either a 20A or 23A 240V bandsaw?
Yes it will operate it fine.
If you are building a woodworking shop that will have several 240V tools can you install multiple 240V outlets on the same 30A circuit if only one or two tools will be running at the same time?
Yes you can have multiple 220 outlets, but if you are using multiple saws and start kicking your breaker, do not put a bigger breaker in to keep it from tripping you'll break up the protection inside of your wire, and then you'll have major problems. If it don't burn down. If you do start tripping the breaker you will need to run another circuit. Don't just "get used to resetting it." It is a very bad habit and will possibly wear your breaker out. -- HMM... not so sure about that. Maybe that's how they do it where nobody cares. It's against most electrical codes to put more than one 240V appliance on a single circuit, or even to create the possibility by adding receptacles. The simple answer would be to either add a circuit (within the limits of the panel and service) or to unplug one tool and plug the other in.
A W pf capacitor is connected into a 240 V Hz circuit. what is the current flow in this circuit?
a 30 pf capacitor is connected into a 240v, 60 hz circuit. what is the current flow into the circuit
Is there adapters for 250 volt to 120 volts?
No. There are no "adaptors". To get 240V from a 120v supply you use a 120-240V step up transformer. <><><> Clothes dryers, water heaters and and other high-power 240 volt appliances cannot be run on a transformer from a 120 volt circuit. They must be powered from a separate branch circuit that has the right size breakers, cable and socket outlet to suit the appliance.
If you have bought 2 appliances that require 240v outlets each and you only have one what is the easiest and efficient thing to do?
The easiest thing to do is use the appliances one at a time. If you need to use them simultaneously, then the ONLY safe way to do it is to have a qualified electrician add a second complete circuit for the second appliance.
How many 64watt fixtures can a 20amp 240v circuit support?
At 80% load factor you can support 60 fixtures.
How do you upgrade from 120V 15A to 120V 20A or from 240V 20A to 240V 30A?
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.
Is it possible to run a 240V heater and two 120V outlets from one line of 3 wire 12 gauge romex?
It's possible. It's not right though. Run a separate wire for your 110v circuit. To follow NEC (National Electrical Code) guidelines you need two separate branch circuits: 240V and 120V.Each circuit should have its own breakers of the correct size. Wire sizes will depend on the length and ampacity of each cable.The outlet types required for each circuit will depend on the appliances to be served and, according to their locations, GFCIs may be necessary too. As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
Can you run a 208 volt single-phase computer off 240 volt power?
No. The 1-phase 240 setting on your computer's power supply is for the 240V wall outlets in other countries. The 240 outlets in your home are 2-phase 240.
