• 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 influ-
ence each other with swift load change. For example, normally 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.
