Heaters on One line diagram
Heaters on One line diagram
(OP)
I have couple of 1.1 MW, 480 V heaters that I need to show on single line diagram. What symbol should I use. Can I just use a box and write Heater in it. Or Should I draw a box and write SCR controller in it and connect a circle to it and write 1.1 MW heater in it.
Any suggestions...

RE: Heaters on One line diagram
If the heater and controller are all one device, just use a single box.
At 1 MW+ the heater is probably made up of several smaller heating elements and multiple SCR's in the same panel. Instead of 1 set of large wires from the controller you may have 3, 4, or 5 sets of smaller wires.
