An effect of connecting a poor contact in an electrical circuit could be intermittent current flow.
A "dry" contact is a contact that is not initially connected to a voltage source. It could be stand-alone, such as a pressure switch mounted on a boiler. Or, if the contact is mounted as part of an electrical unit that has a power source, then the "dry" contact has no pre-wired electrical connection to that power source. For example, a magnetic motor starter may have an extra contact that is not connected to the control circuit that starts and stops the motor. However, when the motor starts, the "dry" contact changes state, because the mechanical action of the starter moves the contact. This "dry" contact could then be wired to devices/circuits that are separate/remote from the motor starter circuits. I do not recognize the term "no volt contact" but I suspect that it is the same thing. A specific type of dry contact in the USA is a "form C" contact which is a three wire contact: Normally Open(NO), Normally Closed (NC), and a Common (C).
Circuits are on the ground for a few reasons one is to prevent contact with dangerous voltage if the electrical insulation fails. Also been on the ground limits the build- up of electricity static.
Two answers for this question. An electrical contact is any point in a circuit that a wire connects to, such as a screw or terminal block. The term is also used when referring to control circuits. There are contacts inside Relays, Ligthting contators, and motor starters. They can be called N.O. for normally open, and or N.C. for normally closed. They "Make" of "Break" and electrical circuit.
Electrical conduit is a system of pipes, tubes, or channels used to protect and route electrical wires in buildings, homes, and industrial settings. It serves several critical purposes: ●Protection: Conduit provides physical protection for electrical wiring, cables, and conductors, shielding them from damage due to impact, moisture, chemicals, and other environmental factors. It helps prevent accidental contact with live wires, reducing the risk of electrical shocks and fire hazards. ●Routing and Organization: Conduit helps in organizing and routing electrical wires and cables in a structured manner. It allows for neat and orderly installation, making it easier to identify and trace specific circuits or cables when troubleshooting or making changes. ●Grounding: Conduit systems can serve as an effective grounding path for electrical equipment and circuits. By connecting metallic conduit to grounding systems, it helps to dissipate electrical faults and provides an additional safety measure against electrical faults and surges. ●Future Flexibility: Conduit installations offer future flexibility by allowing for easy modification, expansion, or replacement of electrical wiring and cables. It simplifies the process of adding or upgrading electrical systems, reducing the need for extensive rework and minimizing disruptions to the existing infrastructure. That's it.
There is a heated bimetallic strip that provides a time delay small overload protection. When its contact makes, it energizes a coil to trip the breaker. Some breakers are mechanical, though. There is a coil that trips the breaker instantly on large overload.

A wire nut or terminal block is commonly used to join two electrical conductors in order to securely connect them and prevent electrical contact or short circuits.

It's essential to turn off electrical connections to ensure safety and prevent electrical shock or injury while working on or near electrical systems. De-energizing circuits minimizes the risk of accidental contact with live wires, which can lead to serious accidents. Additionally, it helps protect equipment and prevents potential short circuits or electrical fires during maintenance or repairs. Always follow safety protocols and use proper personal protective equipment when handling electrical connections.

An extraneous conductive part is any conductive object or material that comes into contact with electrical circuits or components, creating a potential safety hazard. These parts can unintentionally carry current, cause short circuits, or interfere with the normal operation of electrical systems. Proper grounding and insulation techniques are essential to prevent extraneous conductive parts from causing problems.
In the electrical industry, there are a variety of different uses for electrical lugs. Electrical lugs help provide the supply and distribution of electrical current without creating any hindrance between the electrical cables they’re connecting. Electrical lugs are often used when it isn’t possible to permanently connect two wires. Some of their most common uses include connecting two or more electrical cables, as well as connecting fuse sockets, load switches, and electrical appliances. Traditionally, only one end of an electrical lug is used to connect a cable to an electrical device. One end of the lug is soldered, crimped, or welded to ensure it’s installed properly and the other end of the lug is connected to the device.When it comes to finding high-quality electrical lugs for your application, contact the team from Greaves Corporation online today.

The distance between the neutral and ground pins in a plug is not the same to prevent accidental short circuits or contact between the neutral and ground wires. This helps to ensure safety by reducing the risk of electrical shocks or fires. Additionally, it helps maintain the proper functioning of electrical circuits by preventing interference between the neutral and ground connections.
A live wire coming in contact with a ground.
Charging by contact can be dangerous when there is a risk of electric shock, such as when using damaged cables or connecting to a power source with improper voltage. It is also hazardous if the device being charged overheats or catches fire due to issues like short circuits. Additionally, charging in wet or humid conditions can increase the risk of electrical accidents.

Electric shock: Contact with electrical currents can cause injury or death by disrupting the body's natural electrical signals. Fire hazard: Overloaded circuits, faulty wiring, or damaged appliances can lead to electrical fires. Electrical burns: Exposure to high voltages can result in burns to the skin and underlying tissues.
