DB board upgrades and earth leakage, Vanderbijlpark and the Vaal.

Your board is the safety part of your house. I replace single-phase boards, and the Certificate of Compliance is included in that price. I also fit earth leakage units, breakers and surge protection at the board. WhatsApp me a photo of your open board and you get a written price back before I start anything.

WhatsApp DanieSend a photo of the board with your message. Quoting costs nothing. Only open the cover if it is safe, otherwise photograph it closed.

Wat's stukkend? nine warning signs at the board

Nine things I look for.

These are the signs an ageing board gives you before it gives up. Tick two and send me a photo. Tick the first one and phone me instead of typing.

  1. A burning smell, or scorch marks.

    Brown or black staining around a switch. Stop. Switch the main off and phone me. Don't wait for the next storm.

    Rather phone than type: 072 839 6259
  2. Buzzing or humming from the board.

    A breaker that hums is a breaker that is not gripping properly.

  3. Switches that feel warm.

    Warm plastic means a loose connection heating up behind it.

  4. Lights dim when the kettle or the pump starts.

    The board or the supply cable is working harder than it was built for.

  5. Trips that keep coming back.

    Once is a fault. Every week is a fault plus a board that can't tell you where it is.

  6. No earth leakage unit at all.

    Very common in Vanderbijlpark houses from the 1950s to the 1970s. This is the switch that saves a life.

  7. Rust or corrosion inside.

    Outside boards take rain for forty years and then let it in.

  8. Wire fuses or old ceramic holders.

    If somebody once fitted the wrong wire, there is no protection left at all.

  9. Switches nobody can name.

    An unlabelled board is a board nobody can switch off safely in an emergency.

Press the test button on your earth leakage. Once a month. If it doesn't trip, it isn't protecting anybody.
Takes about thirty seconds

That test is the one job on this page you can do yourself. Find the small button marked "T" or "test" on the earth leakage unit and press it. The power should go off straight away. Switch it back on. If nothing happened, the unit has failed and needs replacing. Send me a photo of the board and I'll price it on WhatsApp.

Plenty of homes still run boards fitted in the 1990s, sized for a house with one TV. Now there are three TVs, two computers, an air conditioner and a pool pump on the same board. Add forty years of switching and the parts inside simply wear out.

Prices what actually decides them

What decides the price of a board.

I don't publish a list, because no two boards are the same job. What changes the figure is the size of the board, how many circuits it feeds, whether the cable into it is sound, and what I find behind the cover once it's open. You get the exact figure in writing before I open anything up.

You'll see frightening numbers quoted for a board upgrade on some websites. A single-phase board is a boxful of parts and the labour to fit them properly, and that's what I price it as. Send me a photo and I'll tell you what yours needs.

Careful of the cheap "board special". A board swapped without testing the circuits behind it is a new box on old problems. Mine comes with the test readings, so you can see what your circuits actually measured.

Iscor-era housing the boards I open every week

Built for a bulb and a stove.

Vanderbijlpark was built around the steelworks. Whole suburbs — CE, CW, SE1 to SE7, SW — went up between the 1950s and the 1970s as Iscor housing. Solid houses. Good brickwork. Boards designed for a stove, a geyser, a few lights and one plug in the lounge.

Here is what I actually find in them. Rubber-insulated wiring gone hard, cracking when you move it. A board with no earth leakage unit, because nothing said it had to have one when the house was built. Six circuits doing the work of twelve. A kitchen added to three times, so the stove, the microwave, the kettle and the dishwasher all sit on one thin cable.

None of that means your house is dangerous today. It means your board was sized for 1965 and your house lives in 2026. That gap is the whole job.

Sasolburg and Vaalpark have the same story with Sasol-built stock. Three Rivers and the Meyerton plots have the opposite problem — big stands, long cable runs, pool pumps and boreholes hanging off boards that were never meant to feed them.

Real photos of my own work go in these two slots — never stock, never AI. You get the same pair of your own board, plus the mid-job shot where you can see what was hiding behind the cover.

The thermal camera. Before I close up, I photograph the loaded board with a thermal camera. A loose connection runs hotter than the ones next to it and shows up as a bright spot — months before it smells or smokes. The image goes in your file.
The insurance argument the one nobody local explains

The outages that kill your TV are the ones you can't claim for.

Read this part twice. It changed in 2023 and most people in the Vaal never heard about it.

Since 2023 most South African insurers exclude loss or damage caused, directly or indirectly, by the interruption, failure or restoration of the electricity supply. Then they carve out one exception: scheduled, phased load shedding that does not hit a whole municipality at the same time.

Now look at what actually happens here. Most of the outages we get are unplanned ones, and an unplanned outage is not scheduled and not phased. So it usually sits outside the carve-out and inside the exclusion.

King Price puts it plainly: grid interruptions come without warning, unlike load shedding, which makes them harder to prepare for. Their own remedy is surge protection fitted at the distribution board by a qualified electrician. Santam tells homeowners the same — fit surge protection at the board or at the outlets — and it no longer waives your excess for having it.

I will never tell you a claim is guaranteed. No honest electrician can. What I can tell you is that the hardware is the part you control, and at the board it is a few hundred rand of parts.

Read your own policy wording. Search it for the words "interruption", "restoration" and "load shedding". WhatsApp me the paragraph and I'll tell you in plain language what it means for your board. Free, and no, I don't sell insurance.

Southern Gauteng sits in the 10 to 15 flashes per square kilometre per year band — the higher of the two Highveld categories. The storm season runs October to March, with the afternoon thunderstorms everybody here knows in November, December and January.

Book the board check in September, October or November, before the first big storm. That's when I have diary space and you still have a choice.

What happens on the day how I work at your board

Plant standards
at your board.

On a Sasol plant you don't work live and you don't guess. Same rules at your house. It adds ten minutes, and it is why nobody gets hurt.

Step 01 · before I start

Isolate.

Main switch off, locked, tagged, tested dead. The key stays in my pocket, so nobody switches it back on while my hands are in the board.

Step 02 · the work

Rebuild.

New board, correct breakers, earth leakage protection, a surge device if you chose one, and every circuit traced and labelled by name — not "circuit 4".

Step 03 · before I leave

Test.

Earth continuity, insulation resistance, polarity and the earth leakage trip time. Then the thermal image, and the certificate with the test report and the readings on it.

The certificate comes with the board. Your new board is certified after the physical inspection and test, with the test report and the readings on it. Who signs it is set out in the footer, and you're welcome to phone the Department of Employment and Labour on 051 505 6371 to check the number.
Three-phase or commercial property? Not a problem. Just tell me what the property is and I'll sort it out.
Straight answers the board questions I get every week

Before you phone.

How do I know my DB board is too old?
Look for wire fuses or old ceramic holders, no earth leakage unit, brown or black burn marks, a faint burning smell, rust, buzzing, warm switches, or switches nobody can identify. Houses wired in the 1950s to 1970s often have several at once. Send me a photo of the open board and I'll tell you what I see. Free.
What does an earth leakage unit actually do?
It compares the current going out with the current coming back. If about 30 milliamps goes missing, it switches your power off in a fraction of a second. That missing current is usually going through a person or into wet wiring. Press its test button once a month. It must trip. If it doesn't, the protection has failed and the unit needs replacing. Send me a photo of the board and I'll price the replacement on WhatsApp.
Why does my earth leakage trip when the power comes back on?
When the supply is switched back, the spike and the imbalance in the neutral can push a tired unit over its trip point. Small leaks from several appliances do the same thing — three small leaks together cross the 30 mA line. I test the unit properly and isolate one circuit at a time instead of guessing. That's a fault I have to find, so it's priced on site: R300 to come out, and a written price before I do anything.
Will surge protection stop lightning damage?
No, and anyone who says otherwise is selling. A device at your board handles induced surges — the spike that comes down the street wiring when the supply is restored, or when lightning hits nearby. A direct strike on your house is another matter. The sensible setup is layered: one device at the board, plus plug-level protection on the TV and the computer.
Will my insurance pay if an outage damages my appliances?
I can't promise that, and I won't. Since 2023 most SA insurers exclude damage caused by the interruption or restoration of supply, and carve out only scheduled, phased load shedding that doesn't hit a whole municipality at once. An unplanned outage is neither, so it usually falls outside that carve-out. Read your policy. Then fit the hardware, because that part is yours to control.
Do I get a Certificate of Compliance with a new board?
Yes. The board replacement price includes the Certificate of Compliance for the installation, issued after a physical inspection and test. The test report with the readings comes with it, and that is the paperwork a conveyancer or an insurer actually asks for. On its own, without a board replacement, the certificate is R3 000 for the first DB board.
Who signs my CoC?
A registered person inspects, tests and signs the certificate, and I do any electrical repairs needed to pass. Their name and registration number are printed on it, so you can check them with the Department yourself. Three-phase and commercial properties are done too. Just tell me what the property is.
How long is my power off?
The supply has to be off while I'm working inside the board. I tell you the day before, and again when it goes off and when it's back on, so you can plan the fridge, the freezer and anyone working from home.
What is the thermal-imaging check?
With the board switched on and loaded, I photograph it with a thermal camera. A loose or failing connection runs hotter than the ones beside it and shows as a bright spot long before it smells or smokes. You get that image with your paperwork.
Praat jy Afrikaans?
Ja, natuurlik. Stuur 'n foto van die bord op WhatsApp, in Afrikaans of Engels — jy kry dieselfde reguit antwoord en 'n prys op skrif.

Tell me what's
happening.

A photo of your open board tells me whether it needs a breaker, an earth leakage unit, a surge device or the whole board. If it turns out to be a fault behind the board, I find that on site and price it there.
