Can you wire 2 bedroom on 1 breaker?
You can't wire 2 beedrooms on one breaker.
Can multiple circuits be connected on one breaker?
Multiple wires can be connected to one breaker but the one breaker IS a circuit. As long as the load is not more than 80% of the breaker capacity (example: a 20 amp breaker can only have 16 amps or 1920 watts at 120 volts) then by code as long as the load is not a specialty outlet of some sort, you can have as many outlets you want.
What does dwell mean?
The number of degrees the breaker cam rotates from the time the breaker points close until they open again.
The probability that a tennis set will go to a tie breaker is 10 percent what is the probability that two of the three sets will go to a tie breaker?
The outcomes for each set is not independent. For a set to go into a tie breaker the players need to be very evenly matched. If they are, there is a greater probability that the sets will go into tie breaker. If you disregard that aspect of realitythen the answer is 0.0270, approx.

What best breaker rating for 1.5 hp air con unit?
The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
What best breaker rating for 1.5 hp air-con unit?
The breaker you use is determined by the size of the wire in the wall not by what is being connected to that circuit. If you have 14/2 wire then use a 15 amp breaker. If you have 12/2 wire then use a 20 amp breaker. The breaker protects the wiring not the item connected.
What size amp circuit breaker should be used for 110 outlet?
The size breaker you use is determined by the size wire used in the circuit. If you use AWG #12/2 wire then use a 20 amp breaker. If you use AWG # 14/2 then use a 15 amp breaker.
How do you calculate rated kva of a circuit breaker?
You don't calculate the rated kV.A of a circuit breaker; it's determined by the manufacturer. It's important that a circuit breaker's rated kV.A exceeds the fault level kV.A at the point where the circuit breaker is located, otherwise it may fail to interrupt a fault current and, possibly, self destruct.
What size breaker do you need for 9000W at 440V 3phase?
This formula will give you the amperage I = kw x 1000/1.73 x E x pf (pf = power factor). Take the amperage and multiply it by 125%. This will give you the breaker size that you need.
What amp breakers need to go on your outside electrical box?
The size of the breaker is determined by the smallest conductor used in the system and by the type of load being serviced.
Why does the surge protectors circuit breaker trip if a surge or overload is detected?
A circuit breaker shuts off the power to an electrical circuit when it detects too much current flow. As electricity moves through wiring, an electromagnetic field develops around the wire. Electromagnetic breakers capitalize on this field production by using electromagnets. The current that moves through the breaker charges the electromagnet and as the current increases the magnetic pull also increases. If the current exceeds the limit the breaker is designed to handle, the magnetic pull becomes strong enough to pull the contact plate away from the stationary plate. This breaks the circuit and is referred to as "tripping the breaker. A surge protector on the other hand prevents a voltager higher than the normal voltage from damaging electical devices. It does not shut off the power as a circuit breaker or fuse does.
How do you run dedicated 240V lines for power tools?
Answer for USA, Canada and countries running a 60 Hertz supply service.One 240 volt receptacle fed from a two pole breaker from the distribution panel. The size of the breaker is determined by the load current and the wire sized accordingly.

How do you replace a 15 amp breaker in the circuit box?
The breaker will have a black wire connected to it. Turn off the main breaker and then disconnect that black wire from the breaker. The breaker will snap into the main bar. Remove the breaker and install the new one. Reconnect the black wire to the breaker and then install the cover and turn the main breaker back on.
