You would like to install a 30 amp circuit and you have a open slot from a attic fan which no longer is needed and is 15 amp but how do you know if the 200 amp box can handle it?

Why the force needed to undo the bolt is smaller when a spanner with a longer handle is used?
Basically, the longer the handle, the less force is needed to apply a certain torque. This is defined by the equation t=fd where t= torque, f= force, and d= distance in a radial fashion.
What size circuit breaker is needed for a 300 watt bulb?
A 15 amp circuit breaker will handle this situation very well. The smallest home breaker is rated at 15 amp.
How do you determine height of toilet flanges and floor drains prior to the concrete being puored?
By strict calculations OR install the pipe longer then needed and after the finish work cut the pipe to the required height and install the flange
Is a switch needed to make a circuit work?
Not always. Depends on the circuit.
What is needed if a certain circuit in a vehicle caught fire due to a short circuit?
This circuit needed to have a fuse installed before the circuit was energized. Now the circuit is going to need new wiring along with a fuse before the system is re energized.
What pushes the current around the circuit?
A voltage supply is needed to operate a circuit.
Why is earth wire not needed in a light circuit?
A ground (earth) wire is needed in not just a light circuit but in all circuits that are now installed.
Were does a phlebotomist work?
No because the "patients" you will find at a funeral home no longer have a working blood flow. A coroner will handle all tests needed to be preformed.
What jobs dose a battery do in the circuit?
The purpose of the battery in a circuit is to wive energy to the circuit
Can the fittings attach to any wall or will I need to purchase items from a hardware store to install this item?
You will need to buy several longer screw to get the added security needed for the mount.
What is the effect on the effort force used when the length of the effort arm is decreased?
The force you are referring to is called torque. here is an example: you have 2 wrenches, one with a short handle and the other with a long handle, and 2 identical bolts. The force required for the longer wrench to turn the bolt is less than the force required for the short to turn the bolt. This is because the longer the handle the greater the Torque and therefore less force needs to be applied. summary: longer "effort arm"=more torque= less force needed shorter "effort arm"=less torque=more force needed I hope this answers your question
Why reset circuit needed in 8051?
You need a reset circuit in the 8051, as in every logic circuit, in order to ensure that it starts up in a known state.
