What We Design Around In Big Bay
Unbroken Sea Wind & Salt Spray
Big Bay sits fully exposed to the Atlantic with nothing to break the South Easter or salt spray, which accelerates corrosion on outdoor DB boards, junction boxes and fittings faster than more sheltered suburbs.
New-Build Double-Storey Homes
Most Big Bay properties are recently built double-storey houses with modern wiring, but that also means larger DB boards, more circuits and higher-spec installations that need correct sizing from day one.
Sandy, Dune-Stabilised Ground
Earthing on Big Bay’s sandy coastal soil behaves differently to clay-based suburbs further inland, so we test earth resistance on-site rather than assuming a standard result.
Why A Big Bay Electrical Job Isn’t A Standard Cape Town Callout
Big Bay is one of Cape Town’s most wind- and salt-exposed suburbs, sitting directly on the Atlantic north of Blouberg with nothing between the properties and the sea. That constant salt-laden South Easter accelerates corrosion on outdoor electrical components far faster than in sheltered suburbs, and the newer double-storey homes that dominate the area carry larger, higher-spec distribution boards than older Cape Town housing stock.
Corrosion-Resistant Outdoor Work On The Coast
Outdoor plug points, garden lighting circuits and DB enclosures facing the sea age faster here. We use corrosion-resistant fittings and check outdoor circuits more closely on every Big Bay visit.
Wired For Big Bay’s New-Build Homes
Many Big Bay properties were built in the last decade with larger DB boards and more circuits than older Cape Town homes. We size any new work to match the property’s full electrical load, not just the fault in front of us.

Beyond The Callout — We Maintain It Too
At Thermo Group, our relationship with our Big Bay clients doesn’t end when the job is signed off.
We offer ongoing electrical inspections and fault-finding for Big Bay properties. Our team can assist with DB upgrades, earth leakage issues, rewiring and general electrical maintenance.
Regular checks can also help identify potential problems before they cause an outage or a compliance issue.
Electrical Certificates & Compliance
A working installation and a compliant one aren’t always the same thing. If you’re selling, renovating, or simply want peace of mind, your property may need an Electrical Certificate of Compliance (COC).
Thermo Group can assist with the inspection, any required repairs, and the compliance certificate itself, so you deal with one team from fault to certificate.
Our goal is to make the process as straightforward as possible for the property owner.
