Mechanical vs Electrical Engineering in South Africa
Students often compare Mechanical and Electrical Engineering because both are core BEng degrees with strong job prospects. But they focus on very different systems: Mechanical Engineering deals with physical motion, forces, and thermal systems (e.g., engines, robotics), while Electrical Engineering focuses on power, electronics, and control systems (e.g., circuits, renewable energy, automation). This guide helps you choose based on your interests — not just the title.
Key Differences at a Glance
- Focus: Mechanical = machines, motion, heat | Electrical = power, signals, electronics
- Theory vs Practical: Both are theory-heavy, but Mechanical leans toward physics & design; Electrical toward math & circuit logic
- Career Direction: Mechanical → automotive, aerospace, HVAC | Electrical → power utilities, telecommunications, robotics
- Maths Intensity: Both require strong calculus and physics, but Electrical uses more complex numbers and signal analysis
- Typical Projects: Mechanical = designing a gearbox or cooling system | Electrical = building a power grid or microcontroller circuit
Entry Requirements
Both require Mathematics (not Maths Literacy), Physical Sciences, and English at 60%+. Minimum APS is typically **32–35**, depending on the university. Neither accepts Maths Literacy.

Difficulty & Workload
Both are demanding 4-year BEng degrees with heavy workloads. Mechanical Engineering involves more hands-on labs (materials testing, thermodynamics), while Electrical has more abstract theory (electromagnetism, digital systems). Success in either requires strong problem-solving skills and consistent effort.
Career Paths
Mechanical Engineering graduates work in automotive design, manufacturing, energy (oil/gas, renewables), HVAC, and robotics. They design physical systems that move, transfer heat, or convert energy.
Electrical Engineering graduates work in power generation, telecommunications, electronics, automation, and smart-grid technology. They design systems that generate, transmit, or process electrical energy and data.
Salary Expectations (ZAR p.a.)
| Mechanical Engineering | Electrical Engineering | |
|---|---|---|
| Entry-level | R280,000 – R360,000 p.a. | R290,000 – R370,000 p.a. |
| Average | R450,000 – R650,000 p.a. | R460,000 – R680,000 p.a. |
| Senior / Specialist | R750,000 – R1.3M+ p.a. | R800,000 – R1.4M+ p.a. |
Salaries vary by sector (mining, tech, government) and location. Renewable energy and automation roles often pay premiums.
Which One Is Right For You?
- Choose Mechanical Engineering if you love taking things apart, understanding how machines work, and solving physical design problems.
- Choose Electrical Engineering if you’re fascinated by electricity, enjoy circuit puzzles, and want to work with power or digital systems.
- If you prefer working with tangible objects (gears, engines, structures), go Mechanical.
- If you’re drawn to invisible forces (current, voltage, signals), go Electrical.
- Both lead to professional registration (Pr Eng) and strong long-term careers.
- Consider dual-focus fields like Mechatronics if you can’t decide!
Frequently Asked Questions
Can I switch from Mechanical to Electrical Engineering after first year?
Some universities allow transfers if you pass common first-year modules (Maths, Physics, Engineering Fundamentals). Check with your institution early — it’s easier within the same faculty.
Which has better job prospects in South Africa?
Both are in high demand. Mechanical engineers are needed in mining, manufacturing, and energy. Electrical engineers are critical in power (Eskom, renewables), telecoms, and automation. Long-term, both offer excellent stability.
Do I need to be good at drawing or CAD for Mechanical Engineering?
Basic technical drawing is taught in first year. Proficiency in CAD (e.g., SolidWorks) develops during the degree. Creativity helps, but it’s a learnable skill.
Is Electrical Engineering the same as Computer Engineering?
No. Electrical Engineering focuses on power and analog systems. Computer Engineering (offered at Wits, UP, UCT) blends Electrical with software and digital hardware (like microprocessors).
