I am final, I am sorry, but you could not paint little bit more in detail.

So there is Volts (Three Phase Supply System) between any two phases and Volts (Single Phase Supply) between a neutral and phase (live) wires. Residential load (i.e. Fans, Lights, and TV etc) may be connected between any one phase and neutral wires, while three phase load may be connected directly to the three phase lines. On /V, 3 phase Delta systems, watch out for phase 2, the wild leg. Cannot put volt loads on this phase, because voltage is volts to neutral. Sizing Feeders for Panels 1. Feeders to panels must be equal to or greater than ampacity of main breaker. This assumes short runs with less than 3% voltage drop, copper feeders.

In my opinion you commit an error.

For a three-phase service, divide by *sqrt(3) for the service in amps. Confirm 3phase is available with your utility, but typically the service has to be over amps to justify a three-phase service. Here’s an example of a typical house with a /V 3-wire service. The house is.

In it something is. Earlier I thought differently, I thank for the information.

Distribution substation A distribution substation transfers power from the transmission system to the distribution system of an area. The input for a distribution substation is typically at least two transmission or subtransmission lines. Distribution voltages are typically medium voltage, between and 33 kV depending on the size of the area served and the practices of the local utility. Sizing Motor-Circuit Feeders and Their Overcurrent Protection. For AC single-phase motors, polyphase motors other than woundrotor (synchronous and induction other than Code E): [1], [2] Feeder wire size is percent of motor full-load (FL) current minimum.. Feeder breaker (thermal-magnetic fixed-trip type) is percent of FL current maximum.. Feeder breaker (instantaneous magnetic-only.

I think, that you commit an error.
