Answer for USA, Canada and countries running a 60 Hz supply service.
Do this electrical work only if you feel confident that you can do it safely. If not then this is the procedure that an electrician would use and you would be able to follow what he is doing. Again an electrician should be your first choice.
If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU.
Before an explanation of how to do this you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 120 volts.
The existing two pole breaker in the distribution panel that is to be replaced should not have a larger rating than a 15 or 20 amps. The wire size from that breaker will be #14 or #12 respectively. The final results of this project will leave you with a 15 amp 120 volt receptacle and one spare 15 amp breaker in the distribution panel.
That said, OK, any 240 volt outlet can be changed to 120 volt by removing the white wire from the 2 pole breaker and inserting it into the neutral bus bar. Remove the other wire (probably black) from the breaker. Remove the 2 pole breaker from the breaker panel. Install two single pole 15 amp breakers into the hole left by the 2 pole breaker. Leave both of these breakers turned off.
Connect the black wire that came off of the 2 pole breaker on to one of the new single pole 15 amp breakers. Re install the cover to the electrical panel, this end is finished. At the old 240 volt receptacle, remove the existing device and install a new 120 volt receptacle.
Materials can be purchased at local building supply store. Remember to take the electrical panel data with you so you have the information for the 2 new breakers. Once you have the new 120 volt receptacle installed, identify on the electrical panel door what the breaker is used for. Leave the unused breaker in the off position. Turn the new 15 amp breaker on. Turn the main breaker back on. Test the new receptacle with a lamp to make sure every thing is OK.
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 JOB
SAFELY AND COMPETENTLY
REFER THIS WORK TO QUALIFIED PROFESSIONALS.
Electrical cord is also refered to as power cord, line cord, and main cable. Electrical cord is mainly used to connect the appliance to the main electricity supply via wall socket.
Mainly to prevent electrical shocks to the user of the appliance. Also helps keep the appliance from being damaged. <><><> The purpose of the grounding pin or prong is to connect the metal casing and any metal parts inside the appliance straight back to ground independently to the neutral wire. Then, if ever the metal casing or any metal parts inside the appliance become electrically "hot" or "live" because of an equipment failure, accidental damage - or some other cause of a malfunction - the direct path back to ground will in effect produce an immediate short circuit that will make the fuse or circuit breaker, that is protecting the circuit supplying current to the appliance, to operate to break the supply of current. By doing so, it helps to prevent electrical shocks to the user of the appliance. For more information see the answer to the Related Question shown below.
To answer this question fully the type of appliance has to be stated and its voltage.
The output of a 12 volt transformer is an alternating current (AC). Your adapter is a 12 volt transformer but it has a built in half wave or, more expensive ones, a full wave bridge rectifier. What this rectifier does is change AC to DC. Bridge rectifiers are cheap to purchase. Connect it to the output of the 12 volt transformer and you will get a DC voltage. Great little project.
I think they connect
Yes just connect any line to neutral you have 230volts already.
Electrical cord is also refered to as power cord, line cord, and main cable. Electrical cord is mainly used to connect the appliance to the main electricity supply via wall socket.
How do you connect the transformer's secondary to the bearings.
Yes
Quad ring main unit (QRM) is used to connect 2 no. transformers at their high voltage side to the distribution system.
A network appliance is a home appliance that can connect to control devices wirelessly. Lights can be turned on or ovens pre-heated remotely at the push of a button.
You have to connect each phase (R,Y & B respectively) of earthing transformer zig zag winding to each phase of power transformer delta secondary respectively. Then the zig zag winding of earthing transformer star point to be earthed.
A ground wire is a typically uninsulated copper wire. The intent is to connect the wire to an electrical appliance or fixture to provide electricity a path to ground in the event of a short, thus preventing electrocution.
Lamps use what is called a power cord. Power cords connect the appliance (in this case, a lamp) to a wall socket and the electrical field causes the filiment in the light bulb to beam.
transformers transform
rectifiers have two terminals.it has a circular ring printed on its body.this terminal is negative or n type.but when you connect any terminal of a rectifier to any of the leads of transformer it works reverse.e.g if u connect -ve terminal to the transformer it will give +ve potential,so the other terminal of transformer without rectifier will give -ve potential.
To connect a digital TV converter box, follow these steps:1. Disconnect antenna from TV2. Connect antenna to antenna connection on Converter box.3. Connect an antenna cable from the converter box to the TV's antenna connection.4. Turn the TV to channel 3, turn on the converter box, and follow the setup menu from the converter box to search for channels.5. Keep the TV on channel 3, and change channels using the remote control for the converter box.
