the term isolated refers to a certain section or even a whole circuit that is separated or de- energized from a power source. high voltage lines are often "isolated" by opening swiches or removing jumpers, usually when a section of line is isolated it is because of trouble, problems or dead work. if a circuit is loop fed rather then radial fed, you can isolate a section of damaged line and still keep many if not all customers hot. But don't be confused if a section of line is isolated that does not mean its dead because IF ITS NOT GROUNDED ITS NOT DEAD!
Shut it off and lock it out. Sign the lockout card and keep your key with you.
A cold circuit
No, an electrical approved switch is used to break an electrical circuit.
A complete electrical circuit occurs when it is possible for electrical current to flow through the electrical devices in it.
An open circuit
I have never heard of an electrical term "build" in an electrical circuit.
The term used to designate the point in an electrical circuit where electrical work is done is "load." The load is the component of the circuit that consumes electrical energy and converts it into another form of energy, such as light or heat.
A double pole contactor in an electrical circuit is used to control the flow of electricity to two separate circuits simultaneously. It allows for the isolation and switching of both the live and neutral wires in each circuit, providing a higher level of safety and control in the electrical system.

Ohms Law
The term for a complete electrical path is a circuit. It consists of a closed loop that allows current to flow from a power source to a load and then back to the power source. A circuit can include components such as wires, switches, resistors, and capacitors.
A cold circuit
A parallel circuit
Isolation between power and control circuits is necessary to prevent high voltages or currents from affecting sensitive control components, ensuring safety and reliability of the control system. It also helps in preventing electromagnetic interference and noise from the power circuit, which could disrupt the control signals and lead to system malfunctions.
No, cathodes are negative in an electrical circuit.
