Add up your amps to calculate your breaker size.
Add up your loads (amps), divide by 0.8, and choose that size breaker. If that number does not correspond to a standard size breaker you go to the next higher standard size breaker.

Were is the platinum in a circuit breaker?
There isn't, the contacts in a circuit breaker are plated with silver.
What must you know before you change a circuit breaker?
Before you change a circuit breaker it has to be established that the breaker is at fault and not some other part of the circuit.
What do I do if there is no circuit breaker for outdoor light?
If you have a light that is not being powered through a circuit breaker or fuse, you should call a qualified electrician to remove this circuit from the panel's bus and install a circuit breaker for it. Without an overcurrent protective device (circuit breaker or fuse) you have a potential fire hazard.
Rupturing capacity of a circuit breaker?
the maximum short current that can be safely break by the circuit breaker.
What is Ir value of a circuit breaker?
Ir is the Interrupt rating of the circuit breaker. It is the maximum amount of current the breaker can withstand without damage. In a molded case breaker's electronic trip mechanism, Ir is the continuous current rating that you select, to trip the breaker at a given overload current. Standard requirements request that the breaker trips at 2 hours with an overload of 135% and will trip as a function of I squared x time selected for higher currents.
What size breaker for?
For a standard size refrigerator, a dedicated 15 amp circuit is used.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time . There is a different types of Circuit Breaker's are there 1.According to their arc quenching media these are divided into 4 types a) Oil circuit breaker b) Air blast circuit breaker c) SF6 circuit breaker d) vacuum circuit breaker 2. According to their services the circuit breaker can be divided as a) Outdoor Circuit Breaker b) Indoor Breaker 3. According to the operating mechanism of circuit breaker they can be divided as a) Spring operated Circuit Breaker b) Pneumatic Circuit Breaker c) Hydrolic Circuit Breaker 4. According to the voltage level of installation these are divided into 3 types a) High Voltage Circuit Breaker b) Medium Voltage Circuit Breaker c) Low Voltage Circuit Breaker.

What is the margin of safety with selecting circuit breakers?
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
Is there an error if the upstream circuit breaker is 16A TP and the downstream circuit breaker is 16A TPN?
is there an error if the upstream circuit breaker is 16A TP and the downstream circuit breaker is 16A TPN?
What is a switch that opens a cuircut when too much current is flowing?
Where I'm from, it's called a "circuit breaker".A circuit breaker.
Is a circuit breaker a resistor?
No, a circuit breaker is a safety device that is used in a circuit to limit the amount of current in an overload or short circuit condition. The number on a breaker is the top end current that the breaker will handle before opening the circuit.
What is a non auto circuit breaker?
A non-auto circuit breaker is a circuit breaker with the trip element removed. Basically, it is a modified circuit breaker that is now a disconnect switch (glorified disconnect switch).
Why does the power trip when you test between live and earth?
A standard circuit breaker will sometimes (but not necessarily) trip in such a situation because the amperage exceeds the rating for that breaker. A ground fault interrupt breaker will invariably trip because the amperage on one side of the circuit significantly exceeds the amount returning on the other side of the circuit.
Were is the platinum in a circuit breaker?
There isn't, the contacts in a circuit breaker are plated with silver.
