Hi guys
I have attached a photo of the inside of a very very old motor control panel which i have in a plant where i work. I have no electrical drawing for this panel but in short it is just running a large motor which is running some heavy mixing blades. My question is ,that is piece of kit on the top a very old resistor bank? If so what exactly is it doing. I have never really seen something like this before but to me it looks like it is a large heat sink but i could be wrong. If you look at the photo you can see some cables running from it to the A2 or 0volts on the contactors which are running the motors etc, but again i am not 100% so any input or previous experience would be appreciated.
Ideally i am looking at upgrading this panel to more modern switchgear but i do not want to start on anything until i figure out what this piece of kit is.
Thanks in advance guys.
