It is becoz phase shud be control by switches, and also pahse contain voltages of any ranges.

Why switch is always connected in the phase?
Switches are used to isolate the supply voltage from the connected load. This isolation is needed to be able to work on equipment in the de-energized state. Without the switch in the circuit this could not be accomplished.
Why are push button always connected in parallel in most circuits?
If they were in series in the circuit, they would act as on/off switches.
Flush type and surface type switches?
surface type switches is a switches in the wall while flush type switches is connected in the outlet of appliances. this is the best answer for that!
Are red and brown wires both active?
in 3-phase yesin single phase they may be used for things like 3-way switches in place of duplicate black wires and thus would not always be hot
How do you connected 3 phase motor to single phase power?
Use VFD to make 3 phase from single phase source.
What is the circuit in which two switches are connected in a series?
Two switches in series would be an analogue representation of a solid-state AND logic gate.
What is the difference between a Delta-connected and a Y-connected transformer?
With three windings, you have six terminals. Call them A1, A2, B1, B2, C1, and C2, representing phase A, B, and C. In the delta configuration, A1 is connected to C2, C1 is connected to B2, and B1 is connected to A2. Power is from phase to phase - A1C2, C1B2, and B1A2. In the wye configuration, A2, B2, and C2 are connected together, and are usually connected to neutral. Power is from phase to neutral - A1, B1, and C1.
What is the function of Iron Clad Double Pole switches?
Double pole switches isolate the power by cutting off both phase and neutral simultaneously.
Where can you find a single pole triple throw mini switch?
These types of switches are usually found in three phase installations. When breaking line voltages in a three phase system all three hot legs must be opened to isolate the equipment. These types of switches come in different types for specific uses. Molded case breakers for circuit conductor protection. Non fused switches for equipment transference and fused switches for three phase service entrance equipment.
How many switches can be connected to a contactor coil control circuit?
unlimited
What is a y configuration on a 3 phase circuit?
On a wye connection all three ends of the phase winding coils are connected together and grounded. The other end of the three phase winding are connected to the supply voltage.
On which line is the switch of electrical appliance connected?
A Switch on a domestic supply has always got to be on the LIVE part of that circuit. A double pole switch switches both the LIVE and NEUTRAL off together.
