The mono -pole crusher is a type of circuit breaker that controls a (hot) wire that activates and provides 120 volts protection for a single branch circuit in residential panels. It is commonly used for lighting and exit circles estimated at 15 or 20 amps.
Upon connecting the AFCI AFCI AFCI (Sagittarius Circle Circle Circle), four keys are involved, but only three connected directly: hot, neutral from the circuit, and noise from the crusher. Fourth, the ground wire, connects to the ground strip of the plate, not the crusher.
Correctly enable Breaker AFCI connection function Sagittalist error detection.
Why wires concern AFCI protection
AFCI cutter does not only travel on short circles or overload. He monitors the activity of the current, traveling through both hot and neutral wires. If the shape of an abnormal wave is discovered, it immediately cuts the energy.
In order for this to work, it needs to be broken:
A hot wire provides the current to pregnancy,
A neutral wire that restores this current Through the crusher (Do not exceed it),
Contact the neutral bus to the panel across Braid To complete the inner surveillance circuit.
The collapse of wires and jobs
1. Black (hot wire/download)
• Related to: Download station on AFCI cutter
• It connects directly to the fracture
This current wire from the plate to the devices (vessels and lights) is served on the branch circle. It is the power source for everything in the direction of the river.
2. White (neutral wire from the circle)
• Related to: AFCI neutral station
•It connects directly to the fracture
This conductor carries the return again through the crusher. It should not be landed on the neutral panel tape. Its connection is incorrectly disrupted by the AFCI sensing loop and leaving the arc discovery is ineffective.
3. White of the crusher (installed factory)
• Related to: The neutral bus bar in the painting
• Prerectures on the crusher; You can connect the free end
This properties link the crusher in the plate of the plate and lead to its internal electronics. It should be secured in the neutral bus bar with an open station.
4. The naked or green ground wire (from the circle)
• Related to: Bus tape in the plate
• It does not connect to a break
This safety conductor provides a low -resistance rift pathway. It has no interaction with the discovery of the broken bow, but it is still required to comply with the electric code.
What is the cable used in the AFCI circles wire?
In most residential requests, NM-B (non-metal sheath cable), It is known as Romex, used for AFCI protected branches. This type of cable includes hot and neutral connectors and the combined floor in one sheath and is suitable for internal use in dry sites. It contains all the required conductors and is the NEC option for internal residential use.
The common sizes of the AFCI Cables are 14/2 for 15-APCI Breakers, 12/2 for 20-AP Breakers, and 12/3 for joint neutral equipment with two AFCI sectors or a handcuffed severing in multi-wire branch circles.
