Ultimate Electrical Design Course from Zero to Hero

Estimate building electrical load using built up area, footprint and plot area concepts, then apply diversity and demand factors across Saudi Arabia, IEC, and NEC-inspired methods.

Open AutoCAD and master the basics for electrical design, including menus, command bar, model and layout spaces, and saving drawings as DWG 2013; adjust background and options.

Learn to draw a rectangle in AutoCAD using mouse or the rec command, specifying corners or dimensions, applying area and rotation options, and aligning angles from zero to ten degrees.

Learn to draw polygons in AutoCAD, from squares to hexagons, by specifying sides, center, and radius, and choosing inscribed or circumscribed circle with precise angle control.

Learn how to add and customize text in AutoCAD, including placing text in a rectangle, adjusting size, applying bold, italic, and underline, changing color and alignment, and adding square symbols.

Master the insert, mirror, and scale commands in AutoCAD to reuse blocks, reflect objects, and resize with a base point or a scale factor.

Explore editing AutoCAD drawing properties: color, line weight, and line type; turn on line weight display, and copy these attributes to other objects with match properties.

Master adding and customizing AutoCAD dimensions, including linear, angular, arc, radius, and ordinate measurements, and tune dimension styles, text, arrows, extension lines, and unit precision with quick baseline and continue.

Learn how to enable toolbars and the menu bar in AutoCAD for quick drawing and modification, and configure auto save with backups and the recovery manager to prevent data loss.

Organize electrical design projects with input, output, and draft folders, and prepare architectural drawings by dividing dwg files per floor, grey coloring, hiding axes, and locking layers.

Explore high pressure mercury vapor and metal halide lamps, their white light and CRI ranges, and their use in streets, parking lots, landscapes, factories, gyms, and large interiors.

Discover how light emitting diodes generate light via electro luminescence, delivering cooler, energy efficient illumination; compare LED lifespans and color options with incandescent and fluorescent lamps.

Explore how polar curves and the bowler luminous intensity graph reveal light distribution from a luminaire and guide application-based selection.

Explore how a luminaire can display two polar curves in a 3d view, using solid and dotted lines for 0–180 and 90–270 degrees, guiding proper installation and lighting lux.

Explore color temperature in kelvin, from warm white to daylight and cold white, choosing 2700–3700 K for homes, 4200–4500 K for offices, and 5500–7000 K for galleries.

Design room lighting with manual calculations by determining lux and area, selecting luminaire types, and computing required luminaires using flux, utilization, and maintenance factors, plus spacing and mounting considerations.

Identify building outlines in the site tab with a free drawing tool, capturing X and Y coordinates and distances, then set floor one and location for lighting design.

Navigate the spaces tab in Dialux Evo to create and rename interior rooms, assign offices and utility rooms, and manage floor, building, and site views for accurate lighting design.

Learn to add luminaire catalogs to Dialux Evo, install Philips and other catalogs, and access light fixtures for per-room lighting design.

Define loads and sizes for UBS and lighting circuits using a lighting legend. Replace luminaire blocks in AutoCAD and configure normal versus emergency lighting across corridors and rooms.

Master adding lighting switches in AutoCAD by assigning luminaires to a lighting fixtures layer and using a dedicated lighting switches layer for one- and two-gang switches, including emergency lighting.

Learn to distinguish and label normal and emergency lighting wiring on a schematic, extend and align lines, and create a clear plan that communicates both systems.

Explore how air handling units supply cold air to multiple rooms through ducts, include fresh air handling units for ventilation, and how condensers and evaporators support centralized HVAC across floors.

Explore how pumps, chillers, and air handling units create summer loads and winter loads in an hvac system, and how transformer sizing and distribution panels reflect those seasonal demands.

Learn how sewage and domestic pumps move wastewater from basements to on-site treatment and provide water to upper floors, while MCC panels, VSDs, PLCs, and timers coordinate these pumps.

explore the purpose, rules, and sizing of disconnect switches for motors and equipment per the NEC, including fusible vs non-fusible, marking, and sight-distance requirements.

Explore Siemens disconnect switch ratings, including ampere rating, short circuit withstand ability, voltage rating, and the general duty, heavy duty, and ported pressure types, to select the right switch.

determine the correct non fusible disconnect switch for a combined motor load by summing full-load and locked-rotor currents from NEC tables, then apply 1.15 to size ampere and horsepower ratings.

Select a disconnect switch for a capacitor bank per NEC 460 and 464, using 1.35 times the capacitor current to cover 0–15% tolerance for the bank.

Size weatherproof and non-weatherproof disconnect switches and power sockets for single- and three-phase loads, HVAC and exhaust fans, using NEC guidance for a complete panel plan.

Calculate a panel’s total circuits by adding 20% spare and 10% space to the actual load, then choose the nearest standard panel to accommodate spares and spaces for future expansion.

Balance the three-phase loads across A, B, and C using the ANSI current unbalance rule, adjust single-phase circuits, and derate motors to reduce voltage imbalance.

Explore how residual current circuit breakers detect leakage to ground, protecting people from shocks and fires, in single-phase and three-phase systems, and understand manufacturer specifications such as 30mA thresholds.

Discover low voltage and high voltage fuses for short circuit protection, including low-voltage semi enclosed fuses, kit-kat fuses, hrc cartridge fuses, fuse carriers, and liquid hrc types.
