What are the maximum and minimum heights at which electrical fittings can be fitted?

• A. 450 mm from the floor; 1200 mm from the floor
• B. 60 cm from the floor; 1.5 m from the floor
• C. 300 mm from the floor; 1.0 m from the floor
• D. 450 mm from the floor; 1500 mm from the floor

Answer: (A)

The placement of electrical fittings should be at heights that are practical and safe for everyday use. For most fixed fittings like sockets and switches, a common range is roughly 450 mm from the finished floor up to about 1200 mm.

Reasoning: 450 mm as the minimum keeps outlets low enough to stay out of reach of small children and out of contact with furniture or water hazards, while still being easily accessible. 1200 mm as the maximum keeps switches and outlets within comfortable reach for most adults without needing a stool or ladder.

The other options either set the height too high for convenient use or too low for practicality and safety, so they don’t align with typical ergonomic and safety guidance.
