Today we will talk about the importance of Power Lead and the effect it has on the performance and reliability of your equipment.
Today we are using a satellite 480 grinder and polisher and we are going to use the 4mm squared cable to start with and see what the voltages do and the Load of the machine, and then plug in a regular Bunnings lead and see what happens.
So let’s have a look.
Here we have an example of a regular power lead and the Floorex extension lead. So the difference is in the copper. The heavy duty lead from bunnings normally refers to the outside sheathing not necessarily the copper inside.
So here we have a Floorex lead on the left and a regular heavy duty lead on the right. Floorex Lead is 4mm squared and the heavy duty lead on the right is 1.5mm squared.
Two things we need to be wary of when using extension lead is keeping the length of the lead to a minimum and also making sure there’s enough copper in the lead to carry the voltage through that distance.
So let’s dive in to a real life example now.
We have these Satellite 480 connected to the Floorex extension lead. This is 4mm2. So up on our HVA display we have 239.5 volts available.
Let’s see what happens when we start this machine… OK So we have 230 volts
and is running at 100% This looks excellent
Let’s try now an example where we have a regular power lead plugged into this machine… we have the same power source, so up in the display we still have 239.4 volts with no load.
The key thing is when we put it under load…. The voltage goes right down to 213 volts and the load is sitting at about 130% – 125%
We like to see at least 230 volts and obviously under 100%
So what we’ve seen today is that using a regular power lead from off the shelf could be detrimental to the reliability and performance of your machine and using a Floorex 4mm2 cable can save you a lot of problems with continual resetting and overloading on the machine.
If you’d like more information on this, give us a call we’d be glad to help.
