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.
The term "14-2" typically refers to a type of electrical wire commonly used in residential wiring. It indicates that the wire has 14-gauge conductors and two insulated conductors, usually including a ground wire. This type of wiring is often used for general lighting and receptacle circuits in homes.
"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.
Yes, current electrical codes typically require that knob and tube wiring be replaced when new electrical work is done, especially if it does not meet modern safety standards. This type of wiring is often deemed inadequate and poses safety risks, such as fire hazards. Additionally, many insurance companies may not cover homes with knob and tube wiring, further incentivizing homeowners to upgrade to safer wiring systems. Always consult a licensed electrician or local building authority for specific requirements in your area.
