For circuit breaker what does it mean by AF AT?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
Function of a breaker?
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.
What does it mean RCD?
Residual Current Device. Also known as an Earth Leakage Circuit Breaker or a Safety Switch
Can you use a circuit breaker as a mean of disconnect?
Yes, but I would not recommend it if you are constantly turning the power on/off. If that is the case install a disconnect.
What is mean by auto re-closer in high voltage breaker?
Many high-voltage overhead line faults are temporary in nature -e.g. a branch hitting a line conductor during a storm. An 'autorecloser' mechanism is designed to automatically reclose a circuit breaker after it has tripped. If the fault has cleared itself, then the circuit breaker will remain closed; if not, the autorecloser mechanism can be set to reclose the circuit breaker several times (typically 3) before, finally, locking the circuit breaker open. Autoreclosers are often used in conjuction with 'sectionalisers'; these are non-load breaking switches which will disconnect sections of line towards the end of a feeder, in the hope that any fault has existed beyond that point and will be cleared before the autorecloser recloses the circuit breaker.

What do you mean by acb and vcb?
acb means AIR CIRCUIT BREAKER ,& vcb means VACUUM CIRCUIT BREAKER
What does a draw out circuit breaker mean?
A draw-out circuit breaker is a type of circuit breaker that can be easily removed from its housing for maintenance or replacement without having to shut down the entire system. This feature allows for quick and convenient access to the circuit breaker for servicing purposes.
What is the mean of CKT?
CKT is electrician short hand for circuit. A circuit is everything powerd by on circuit breaker
What does the trip free characteristic of a circuit breaker mean?
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.
What does the ka rating of a circuit breaker mean?
Most times it is the surge current the breaker can withstand in kilo-amps. A normal breaker will see several thousand amps in a short condition. The breaker must be able to withstand and break that current safely.
What does NCL on a cicuit breaker mean?
NCL on a circuit breaker typically stands for "No Connection Left". This indicates that the circuit breaker has no spare or additional connections available. It is important to adhere to the maximum number of connections specified for the circuit breaker to ensure safe and proper operation.
What does 30 amp CB fuse mean?
circuit breaker fuse
What does series D mean on a circuit breaker?
The big yellow "D" is the logo for Square-D, a manufacturer of circuit breakers.
Does a 1993 Suburban have a separate breaker for the turn signals apart from the flasher?
I'm not sure what you mean by "breaker". If you mean fuse, then yes, there is a turn signal fuse in the circuit.
What does the range mean on a breaker box?
The range on a breaker box refers to the maximum amount of electrical current that the circuit breaker can handle before it trips and shuts off power to the circuit. It is important to not exceed the range to prevent electrical hazards and damage to the electrical system.
How many 5 amp TVs can be plugged into a open circuit?
You can plug in as many as you want but none of them will work. An "open" circuit is an electrical circuit which is not a complete circuit and therefore electricity will not flow through it. If you mean an unused circuit,which has no load on it, then the answer is 2 ea. 5 amp devices on a 15 amp circuit and 3 ea. 5 amp devices on a 20 amp circuit. The reason for this is that any circuit is not to be "loaded" more than 80% of the OCPD (circuit breaker amperage rating.
