What is the proper ampere rating of circuit breaker for electric arc welder?
Wiki User
∙ 14y ago
The proper ampere rating of a circuit breaker for an electric arc welder depends on the arc welder. Each is different. Look at the nameplate on the arc welder and choose the circuit breaker and wiring accordingly.

Where would you find or use an earth leak circuit-breaker?
Proper name is GFCI (ground fault circuit interrupter). It could be a breaker or receptacle. It's used for wet location circuits, like bathrooms, kitchens, hot tubs, outdoor
How sf6 circuit breaker work?
As the breaker is tripped, a magnetic coil is beneath it and as the movable contact falls into the coil the arc is elongated in a spiral caused by the magnetic coil until the SF6 quenches the arc.
What is caused by a short circuit?
A short circuit is a low resistance connection where one is unexpected. It causes a diversion of current from the intended load, and, since it is usually a higher than expected current, it often causes the protective device (fuse, circuit breaker, or relay control logic) to trip.
How do you select diode size?
Diodes are usually rated in amperage. A diode may be capable of handling only a 10th of an ampere. Some diodes called Power diodes may be capable of handling up to 100 amperes per diode. To select the proper diode, you must know what the maximum amperage your circuit is capable of. Then you would select one that would handle at least 120 percent of the amperage your circuit would handle.
What will happen if you close isolator after closing circuit breaker while closing the circuit?
If the isolator switch is not load break rated then there could be a phenomena called a flash over, or arc flash. This is a dangerous event. A current will continue flowing through the air gap that is created when opening a switch until the air gap becomes wide enough and the potential on the wire is not high enough to keep the current flowing. Breakers are load break rated in their design. They have magnetic arc chutes located close to the opening contacts that help extinguish the arc when the breaker contacts are opened. So the sequence to use is, open the breaker first and then open the isolation switch. Always remember to lock the isolation switch in the off position when working on the equipment down stream from it.
How do you find the proper circuit breaker for an air conditioning unit?
By reading the manual cocerning circuit amperage
Can a circuit with a GFCI be shared at the box?
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
When installing a circuit breaker, you size the breaker based on the wire size. The breaker should be matched to the ampacity of the wire to ensure proper protection against overloads and short circuits. The device being controlled by the breaker is not a determining factor in sizing the breaker.
Do the making capacity can occur in Low voltage Circuit Breaker?
Unintelligeable...say again in proper English.
What is Trip circuit supervision?
Trip circuit supervision is defined as the protection equipment which monitors the continuity of the trip circuits of a circuit-breaker. The trip circuit supervision relay will monitor the proper functioning of trip circuits.
What is an alternate name for an electric diagram?
There is no "proper name" for an electrical diagram. They are commonly called circuit diagrams.

Definition for time current curve?
It is the relationship between current and time on a circuit breakers opening. When the circuit breaker needs to open in given "windows" of amps and time. They should intersect on the curve to indicate proper circuit breaker functioning. The timing and current value should coincide with each other, per manufacturers specifications. Each breaker differs.
Found 2 wires on a single circuit breaker why?
If it was two wires under one screw on a single-pole breaker, that would not be proper, and most probably against electrical code.If it was two wires, each under their own screw on a double-pole breaker, then that would be a 220 volt circuit; each wire going to its own "leg" of the breaker panel.
Does the code permit the ampacity of switch legs to be less than the ampere rating of the branch circuit?
No, and here's why: the rating of the branch, determined by the overcurrent protection, is designed for the ampacity of the branch conductors so that they breaker trips before the conductors heat up enough to start a fire. If you put in smaller wires on the same branch, they will get MUCH hotter before the circuit breaker trips, if it ever does. For example, a 20A branch, protecting 12AWG wiring; add some 14 AWG rated for 15A. Something faults the switched leg at 18A; enough to burn out the wiring but not enough to trip the breaker. House burns down, insurance doesn't pay because of "faulty wiring" installed negligently by a person without proper training and credentials.
What is a electrical curcuit?
An electric circuit is a path in which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. Its so simple, though my friend from extraminds help me with proper answer.
How do you convert a 4 plate stove which uses a circuit breaker to a wall plug?
You still need a circuit breaker. From your question it appears your stove is hardwired to the panel. It is perfectly acceptable to connect it to a suitably specified outlet and plug for the voltage and amperes for the stove. Basically you would turn off the breaker, install an outlet on the floor or wall so as not to interfere with stove. You can buy cords with the proper plugs and mating receptacles in most any hardware store. For an electric stove with an oven you are usually talking about a 50A breaker and the corresponding outlet and plug. This can be dangerous and if you are not sure of what you are doing an electrician is highly recommended.
