• What’s Single Point Grounding? Maybe you have had an unpleasant
experience while taking a hot shower in Winter. Someone turns on a
hot water faucet somewhere else. You will be impressed with the cold
water! The bottom diagram above shows an example of how devices
will influence each other with swift load change. For example, nor-
mally we turn on all the four hydrants for testing. When you close the
hydrant 3 and hydrant 4, the other two hydrants will get more flow. In
other words, the hydrant cannot keep a constant flow rate.
