Electrical Installation Maintenance and Repair
Electricity Maintenance and Basic Repairs
Maintenance and basic repairs of electrical installations are essential for building conservation.
Basic Electrical Repair Tools and Components:
Electrician’s knife, pliers (flat and cutting), screwdrivers (Phillips and flathead), screwdriver extension poles, wire fish tape, small hammer, duct tape, wire connectors, etc.
Common Electrical Installation Faults:
Short circuits, caused by accidental contact between two conductors, commonly occur in sockets, switches,

Item 14: Manufacturing Operations
Introduction
Manufacturing operations are classified into:
- Hand Tools (filing, sawing)
- Machine Tools (shearing, sawing, drilling, turning, milling, and grinding)
- Factor-cost manufacturing (material loss, energy costs)
Filing
Filing is a manual mechanical operation that shapes metal by removing material. Parts include the ear, body, and tip. Files are classified by shape, size, and type (single or double cut).
Phases:
- Grinding: Uses a coarse file to remove a large amount
Motion Transmission and Conversion Mechanisms
Transmission of Motion
Gears
A gear is a rotating component within a transmission device that transmits rotational force. Unlike pulleys, gears have teeth that mesh with other gear teeth, ensuring complete force transfer without slippage. Gears can modify speed, torque, and direction of force. They are essential simple machines, commonly meshing with other gears or compatible toothed devices like racks.
A key feature of gears is their ability to create a mechanical advantage when gears of different

Identify Opportunity
Identifying a need or problem is the first step to gathering information. Background research helps us understand how others have addressed similar situations. We can consult books, magazines, newspapers, the internet, or personal interviews.
Design
Once an opportunity is identified, we design the new product. This creative stage involves imagining and conceptualizing. Product design includes researching materials, determining shape and size of components, and planning assembly.

Energy Sources
Renewable Energy
Renewable energy sources can be used continuously. Examples include:
- Hydraulic Energy: Water moves wheels and turbines, generating power.
- Wind Energy: Wind turns the blades of wind turbines.
- Biomass Energy: Organic waste is used as fuel.
- Solar Energy: Sunlight heats solar cells, producing electricity.
- Geothermal Energy: Heat from the Earth’s interior is harnessed.
Non-Renewable Energy
Non-renewable energy sources are finite and cannot be regenerated. Examples include:
- Nuclear
Residential Complex Lighting Upgrade in Castro Urdiales
Background
We propose a project to improve the lighting electrical installation of a residential complex. This project aims to optimize the lighting in the complex’s recreational areas, including gardens, tennis courts, and the pool, to achieve greater energy savings. The complex is located in Castro Urdiales, a coastal town in Cantabria, known for its tourism and proximity to Bilbao. The area comprises 4000m², with an 800m² built area, landscaped lawns, trees, a 12×6 community pool, two 23×8 tennis
