Parallel for main circuits and series parallel for lighting circuits.
Romex NM. Is the most widely used electrical wire in homes.
depending on the age of the house, wiring could be several types. Wire known as romex has been used for several years. In very old homes wiring could be two separate wires using glass insulators to separate them.

There are no advantages or disadvantages over which type of junction box to be used on electrical wiring. As long as the junction box is of an approved type (CSA or UL approved). It is cost or location which dictates which boxes will be used. PVC boxes for home wiring are the cheapest. Aluminium or steel are usually used in rigid or EMT conduit systems. PVC again when the conduit system involves underground wiring. In large electrical installations it is the electrical engineer that states what the conduit system type is and what type of electrical junction boxes that must be used.

An electrical contractor does the wiring for homes and businesses. They install the wiring and electrical components needed to run electricity. The question asks about a contactor, not a contractor. A contactor is a type of heavy duty electrical relay for using smaller voltages to control much larger voltages.

Knob and tube wiring is an older electrical system where wires are run through ceramic tubes and secured with knobs. Electricity flows through the wires to power devices in the home. However, this type of wiring can pose safety risks due to its age, lack of grounding, and insulation deterioration. Potential concerns include fire hazards, electrical shocks, and limitations on modern electrical usage. It is recommended to have a professional electrician assess and potentially upgrade knob and tube wiring for safety reasons.

Single phase.
"Plug-on neutral" refers to a type of electrical wiring system where the neutral wire is directly connected to the electrical outlet, making the installation process easier and more efficient.

Romex is a type of electrical cable that contains multiple wires, including THHN wires. THHN wires are single-conductor wires commonly used in electrical wiring. Romex is more suitable for residential electrical wiring as it is easier to install and provides better protection against damage.
series, where the current flows sequentially through each outlet. If one outlet fails, it can disrupt the flow of electricity to all the outlets connected in the circuit. This type of wiring is not commonly used in homes due to the risk of overloading and potential safety hazards.
