We will use the below single line diagram throughout these articles for explaining how to interpret this type of electrical diagrams. In addition to showing the ratings and size of electrical equipment and circuit conductors a properly drawn one line diagram will also show an electrically correct distribution of power with respect to current flow from the power source to the downstream loads or. Central station where power is generated by 3 phase alternators. This is distinct from the local wiring between high voltage substations and customers which is typically referred to as electric power distribution.
A 4 conductor 144 with ground or 124 wg can be used instead of the 3 conductor 143wg to meet this code. Identify electrical wiring and components that may have degraded over time. The single line diagram is circuit diagram where one line is shown to represent three phases of a three phase power system. Reveal if any electrical circuits are overloaded.
Note the followingdead end methods will have one of the 3 way switches missing a neutral which is now required at all switch locations. Pou 4t is a 35kw thermostatic point of use electric tankless water which means it includes ecosmart self modulating technology so it will only consume the energy necessary for the demand.
