We lose appliances to lightning every season. What actually helps?

A layered approach: a surge protective device at the main board, a second stage close to sensitive equipment, and, most importantly, a genuinely low-resistance earth electrode. Surge protection without a good earth has nowhere to send the energy and does very little.

Why does our lighting flicker when the pump runs?

Voltage drop on the long run up from the road connection. On a valley-side plot that cable can be very long, and it was probably sized for the load rather than the distance. Upsizing it resolves it.

Plumber in Kitisuru, Nairobi

We cover Kitisuru including New Kitisuru, Lower Kabete, Kyuna, Loresho, Loresho Ridge, Spring Valley, Thigiri. Off Lower Kabete Road and Peponi Road. Valley-side plots have steep private driveways; we check gradient before committing anything larger than a van.

What is different about plumbing in Kitisuru

Kitisuru's ridge position leaves properties exposed to lightning, so surge protection at the board matters more here than it does lower in the city.
Valley-side plots in New Kitisuru have long buried runs up from the road connection, and voltage drop over that distance shows as flickering under load.
Loresho Ridge houses share the same exposure, and a properly bonded earth electrode with a measured resistance is the foundation of protecting either.

Electrical work in Kitisuru

Kitisuru sits on a ridge with valleys either side, and both facts shape the electrical work here: exposure at the top, distance on the slopes.

Lightning

Ridge-top properties across Kitisuru and Loresho Ridge take a disproportionate share of Nairobi’s lightning damage. Householders lose routers, televisions and inverters season after season and conclude it is unavoidable.

It largely is not, but the remedy is not a plug-in surge strip. It is a surge protective device at the main board, a second stage local to sensitive equipment, and underneath both a properly installed earth electrode with a measured resistance. Surge protection with a poor earth has nowhere to divert energy to and achieves very little.

We measure earth resistance rather than assuming it, and we record the reading.

Distance on the slopes

Valley-side plots sit well below their road connection. The supply run up to the house is long, and where it was sized for load without regard to length the result is measurable voltage drop: flickering under motor load, dim lighting, and equipment running hotter than it should.

Access

Driveways here are steep and tightly turned. We survey access before committing a vehicle, because one that cannot get back out is a larger problem than one that never came.

What we are usually called out for in Kitisuru

Rewiring and electrical installation Full and partial rewiring, consumer unit upgrades and installations brought up to current standard. Emergency electrician An EPRA-licensed electrician 24 hours a day for tripping boards, partial power loss and anything that smells hot. Solar power systems Backup and hybrid solar systems sized against measured consumption, not against a panel count. New house wiring New-build wiring from conduit first fix through to accessories, board and test certificate.
