Breakers that trip with no clear reason, a DB board that feels warm to the touch, a borehole pump that burns out again, or a workshop motor lost to a phase failure: these are the problems behind most requests for control panel installation in Kiambu. The distribution board is where your electrical safety is decided, and many boards across the county were never sized for today's loads.

Nerpax Systems is a Kiambu-based team supplying and installing DB boards and control panels for homes, rental blocks, shops, institutions, farms and industrial premises. We survey your existing board and loads, then fit correctly rated breakers, RCD protection against electric shock, surge protection, three-phase distribution where needed and clear circuit labelling.

Serving Kiambu

Kiambu is home ground for Nerpax Systems, with our base in the Kikuyu area. The county stretches from fast-growing satellite towns such as Ruiru, Juja and Ruaka to tea estates around Limuru, dairy farms in Githunguri and the factories of Thika. That mix shapes the work: rental blocks and student hostels need CCTV, intercoms and well-planned wiring, family homes in new estates want automated gates and electric fencing, and farms far from the main roads lean on solar pumping and backup power when the grid drops. Contractors building across the county also need materials delivered and panels fitted on schedule. We supply, install and deliver throughout Kiambu.

Control Panel & DB Board Installation in Kiambu: FAQs

Do you build pump control panels for farms and boreholes in Kiambu?

Yes. A pump control panel protects the motor from dry running, overload and voltage problems, and can automate pumping with float or pressure switches. We match the panel to your pump and supply, install it and test the full pumping cycle before handover.

What is an RCD and does my DB board need one?

A residual current device switches off the power when it detects current leaking to earth, which can happen when someone touches a live fault. It is a key protection against electric shock. If your board does not have one, we strongly recommend adding it.

Can you replace a DB board without rewiring the whole house?

Often, yes, if the existing wiring is in reasonable condition. We inspect the circuits first, then replace the board and protection while reusing sound cabling. If any circuits are unsafe, we explain what needs replacing so you can decide.
