Electrical design in Nairobi: load calculations, drawings and system design
Good installations start on paper. We calculate loads, size cables and protection, and produce clear drawings, so the system is right before the first cable is pulled and anyone can follow it afterwards.

Ask for a quoteFrequently asked questions
Why do I need an electrical design?
A design makes sure cables, breakers and supply capacity match the real load, gives contractors a common brief and reduces rework on site.
What is a single-line diagram?
A simplified drawing showing how power flows from supply through boards and protection to each circuit and major load. It is the main document used to understand an installation.
Can you design for another contractor to install?
Yes. Our design work can be issued to your own installer or to us.
Do you design solar systems?
Yes, including panel layout, string design, inverter and battery sizing, protection and cabling.
What do I need to start?
Architectural plans if you have them, a list of equipment, and your goals for solar, backup or future expansion.
