• The 5 goals to be considered for electrical design is safety, cost, reliability, flexibility, and quality.
• Electrical Power Source - Sources of electricity that can be utilized by electrical devices.
• Electrical Load Device - Utilizes or consumes electrical power
• Electrical Conductors - Allow electricity to flow from the source to the loads
• Conduits - Tube used to protect and route electrical wiring
• Outlets - A socket that connects an electrical device to a supply
• Switches - Used in circuit to control power
• Protective Device - Used to protect equipment against short circuit, over current and earth fault
• The seven elements of the electrical system: power source, load, conductor, conduit, outlet, switch and protective device.
• The parts of an electrical plan: general electrical requirements, lighting systems, specialized electrical requirements, electrical distribution system.
• US - 120 V, 60 Hz
• Japan - 100 V, 50 and 60 Hz
• PH - 230 V, 60 Hz
• The eight parts of an electrical plan are: general notes and specification, legends and symbols, location plan, riser diagram, schedule of loads and computation, electrical layout, title block, and design analysis.
• Reflection - The bouncing of light off a surface
• Refraction - The bending of light as it passes from one medium to another.
• Below 300K - Warm
• 3200K to 4000K - Neutral
• Above 4000K - Cool
• Color Rendering Index - The degree of color shift objects undergo when illuminated by the light source
• 50 CRI - compact fluorescent
• 80 CRI - standard LED
• 90+ CRI - lux high CRI
• Luminous Intensity - light emitted by the source in a specific direction
• Luminous Flux - light emitted by a source in all directions
• Illuminance - quantity of luminous flux falling on a surface
• Luminance - the brightness of an image, measured in candelas per square meter (candela per square meter)
• Incandescent Lamp - produce light by heating a filament until it glows
• Discharge Lamps - produce light by ionizing a gas through discharge inside the lamp
• Solid-state lamps - converts electrical energy to light through electroluminescence
• Riser diagram shall include the following: lighting and receptacle outlet loads, motor loads, feeders and subfeeders, and load center.
• Schedule of loads and computation shall include the following: motor loads, lighting and receptacle loads, and other loads.
• Light - natural agent that stimulates sight and makes things visible.
