What types of overload protection for circuits in a single family dwelling?
Fuses, Circuit Breakers, GFCI (Ground Fault Circuit Interrupter), Surge Protector, etc.
Getting no power from gfci outlet line?
A GFCI outlet has a TEST and RESET switch. Press reset and see if it fixes problem. If reset won't stay in that means that a ground fault condition is present and may be on another outlet that is fed from the tripped GFCI. If this isn't the problem check the main breaker feeding the GFCI and ensure it isn't tripped. If none of this works the GFCI itself may be bad. If you have a Volt Meter you can remove the outlet from the wall receptacle and make sure there is voltage present. You can also see if there is a branch circuit connected. To troubleshoot you can disconnect the branch circuit and then try reset. If you have voltage on input and GFCI won't reset with branch circuits removed, replace the GFCI.
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
Can a circuit with a GFCI be shared at the box?
Your question is a bit vague, but let's try a two part answer. If you have a GFCI breaker in an electric panel you should only have one connection at the breaker, but the breaker will protect all devices on the circuit. If you are talking about a GFCI outlet, they are equipped to extend the GFCI protection to other non-GFCI outlets by using the proper "output" connection on the GFCI.
Are gfci plugs required in a bathroom?
Deoends on code you are governed by. In USA, a GFCI outlet or a circuit controlled by a GFCI circuit breaker would be required.
What device senses short circuits and stops electrical flow when ground fault occur?
It is a Ground Fault Circuit Interrupter or GFCI. It can either be equipped in your electric panel as a GFCI breaker, or in a GFCI outlet which also lets you extend the GFCI protection to other outlets "down the line" from the GFCI outlet.
Are Ground fault circuit interrupter GFCI devices available for use on 240 volt 480 volt and 600 volt circuits?
Yes, in the form of GFCI circuit breakers, not as a receptacle.
The device used to deenergize circuits automatically when a very small ground-fault flows is the?
Ground Fault Circuit Interrupter (GFCI).
Where is a GFCI not needed?
In rooms without exposure to water such as a bedroom or living room. Typically, GFCI is used in bathrooms, kitchens, garages, outdoors and sometimes basements.
What materials are needed in constructing a plant nursery?
you need greenhouses/hoop houses and trees, shrubs, perennials

Can you use a GFCI on an unswitched circuit line red that uses the same neutral white for a switched circuit coming from the other phase line black in a 240v breaker panel?
Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
Why should a ground fault interrupter be used with portable electric motor?
Unless the motor is used for SPA/pool type use, it does not need a GFCI. Motors can cause nusiance GFCI trips due to sparking at start up. Ideally motors should be operated on dedicated circuits.

How much amperage is needed to trip a 20amp GFCI outlet?
A GFCI trips when it detects a difference in the amperage going to the outlet and what is coming back. Even 4-6 miliamps difference will trip the outlet.
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
In US or Canada are RCDs or updated GFCIs now used with 240 volt balanced household AC power mains supplies to trip on any significant difference between the currents flowing in the live and neutral?
Yes. In Canada no, the main incoming service is not protected with GFCI's. The code calls for selective branch circuits to be protected. In the new code regulations the GFCI's will be replaced with arc fault protection to monitor the selective circuits.
