INTRODUCTION :
Electrical wiring is an electrical installation of cabling and associated devices such as switches, distribution boards, sockets and light fittings in a structure. Wiring is subjected to safety standards for design and installation. Allowable wire and cable types and sixes are specified according to the circuit operating voltage and electric current capability, with further restriction on environmental conditions ,such as ambient temperature range, moisture levels, and exposure to sunlight and chemicals .
Associated circuit protection, control and distribution devices within a building’s wiring system are subject to voltage, current and functional specification. It is necessary to select proper type of wiring scheme for the domestic purpose. Thus a network of wires connecting various accessories for distribution of electrical energy from the supplier meter board to the numerous electrical energy consuming devices through controlling and safety devices is known as Electrical wiring.

Domestic electric circuits:
1.Electric power is usually generated at places which are far away from the places where it is consumed . At the generating station, the electric power is generated at 11KV volts . This voltage alternates at a frequency of 50HZ.
2.The power is transmitted over a long distance at high voltages to minimize the loss of energy in the transmission.
3.The electric power line enter our house through three wires -namely the live wire, the neutral wire and the earth wire.
4.To avoid confusion we follow a colour code for insulating these wires.
5.The ted wire is the live wire, and the black wire is neutral, the earth wire is given green plastic insulation.
Domestic wiring
1.The live wire has a high potential of 220V whereas the neutral wire has zero potential .Thus the potential difference between the live wire and the neutral wire is 220-0=220V.
2.The earth wire is much thicker in size and is made of copper. One end of it is connected to a copper plate buried deep under the earth. The earth connection is made to the electric meter and then the main switch.

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and interrupt current flow. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
