Power Guide
A useful power guide for South African machine floors, including supply checks for industrial workshop equipment.
How Power Guide matters on an install week
The Power Guide helps workshops check whether a machine suits the available electrical supply on site. It covers the points to confirm before installation, including phase, voltage, isolators, and cable access at the machine position.
Before a machine is moved, match its electrical demand to the supply available at your site. In Johannesburg workshops this usually means checking whether the machine needs 380V to 415V three-phase, what isolator is fitted, and where the cable must enter the machine. Dust, older distribution boards, and shared factory feeders can all affect installation planning.
Take clear photos of the incoming supply, the isolator, and the space where the machine will stand. A quick record of the breaker size, plug type, and cable route helps when comparing a lathe, boring machine, or valve grinder against the supply on hand. That makes it easier to spot missing connections before the machine arrives.
Checks before machine connection
Confirm phase, voltage, access for cabling, and any known electrical faults at the installation point. It is also useful to note whether the machine position is close to the main board or whether a longer run and extra protection may be needed. On heavier equipment, the electrical side can be as important as the lifting plan.
Use the Power Guide to gather the key supply details and send them through the contact form. Include the machine type, the available phase on site, and any damage or missing electrical parts visible on the machine. If an isolator, motor plate, or control panel cannot be read clearly, say so.
- Three-phase and voltage noted clearly
- Isolator position photographed at machine bay
- Known electrical faults listed upfront
South African supply points to verify
Many sites around Johannesburg have older three-phase infrastructure, so it helps to check board labels against the actual machine requirement. A machine from Crown Mines may be suitable mechanically, but the install still depends on the supply available at the customer premises. Cable length, isolator rating, and access for an electrician should be recorded before transport is arranged.
Note breaker trips and previous motor repairs. Coastal sites may need closer attention to terminals and corrosion, while inland workshops often deal with dust inside panels and around contactors. If the machine bay is tight, note whether the cable has to pass behind guards, coolant tanks, or existing equipment.

Power Guide for install planning
Use the power guide for site photos, supply details, and any electrical faults already known. Keep the subject line clear.
Keep it with the machine file when preparing for delivery or inspection. It gives one place to capture supply details, photos of the connection point, and any questions about motors, starters, or missing electrical gear. For used equipment, that record is useful when checking what still needs to be fitted on site.
