What Are The Power Requirements For Your Concrete Grinder?

So What Are The Power Requirements For Your Concrete Grinder?

The stronger the concrete grinder, the more power is required to operate it. So always make sure that you have the correct level of power on-site to power your equipment, as well as the correct cable and cable length. When using a 10 AMP Power Cable to power a walk-behind concrete grinder, it’s important to remember that your cable should be 30 metres long MAX. Otherwise, it will trip out your power constantly and won’t power the concrete grinder correctly. When using a powerful concrete grinder, mostly on larger jobs, you will need 15-AMP or Three-Phase power on-site.

When using concrete grinders in situations where there is no power on-site, it’s best to hire a 16 – 45 KVA generator as well as a heavy-duty 10 AMP or Three-Phase Power 30 Metre long cable to ensure the machine is getting enough power.

– 10 AMP Power Cable (Your standard Australian power cable used for most household appliances, they are also used to power handheld and low power 240v walk behind Concrete Grinders)

– 15 AMP Power Cable (This cable looks like a 10 AMP power cable, but the bottom pin is larger. 15 AMP power cables are used to power mid-range Concrete Grinders that require power sources over 240v)

– Three-Phase Power Cables (This is a heavy-duty, large 4-spike cable used to power heavy-duty commercial Concrete Grinders)
