Services & DistributionQuestion 91 of 521
In a typical utility service arrangement, the electric meter (metering equipment) is normally connected:
a.On the load side of the main breaker
b.After the first branch-circuit panel
c.Inside the sub-panel only
d.On the supply (line) side of the service disconnecting means
Explanation
Metering equipment is generally located on the supply side of the service disconnect so it measures all energy entering the premises. Placing the meter on the load side of the main or after a panel would fail to record the total service usage, which is why utilities require line-side metering.
