Maintenance, COCs & Generators
Planned and reactive maintenance for shopping centres and industrial sites, compliance testing and certificates, generator and standby connections, and new supplies.
What we do
Most of our work is for property owners who need one electrical contractor they can call for everything on a site: the monthly list of repairs, the urgent fault, the COC for a new tenant and the bigger upgrade. We keep a record of each site, so the next job starts with what we already know.
- Planned maintenance for centres, offices and industrial sites
- Reactive repairs and fault finding, including extraction fans and motors
- Compliance testing and certificates of compliance (COCs)
- Generator studies: sizing a set from the site's real load
- Generator and standby connections, changeovers and feeder cables
- New supplies and sub-mains, with cable sized on voltage drop
- Site reports with photos and costed recommendations
Recent work
Generator study
Worked out the centre's real load and showed a 100 kVA set would run at 16 to 27% of its rating, deep in wet-stacking territory. We recommended a 40 to 60 kVA set instead.
Standby supply to 13 stores
Designed a metered standby supply from the generator to 13 store circuits, including a 316 m feeder sized on voltage drop rather than on the breaker.
Completed-works list
Thirteen maintenance items from the centre's list, done and quoted back in three batches to match their order process.
Extraction fan repairs
Two failed extraction fans removed for repair and a motor replacement, then refitted.
Frequently asked questions
Do you do maintenance contracts?
Yes. We look after several shopping centres on an ongoing basis, from monthly repair lists to urgent faults, with one point of contact.
Can you issue a COC for an existing installation?
Yes. We inspect and test the installation, fix what does not comply, and issue the certificate once it passes.
How do you size a generator?
From the site's actual load, not the size of the main breaker. An oversized set costs more to buy and run, and suffers from wet-stacking at low load.
What are your working hours?
Monday to Friday, 07:00 to 17:00. Planned shutdowns are scheduled outside trading hours where the site needs it.
Where we work
Based in Germiston and working across most of Gauteng.
