    What is the amperage rating of the socket? 32A maybe? What power is single lamp?

    Edit:

    Divide Watts of single lamp with phase voltage (voltage between any phase and neutral). That's amperage per 1 lamp. Multiply by 28 to get total amperes. Compare the result with rating of the socket.

    Example:

    Socket 16A

    Grid is 3-phase 220/380 V

    28 lamps 100W each.

    amperage of 1 lamp is 100/220=0.45A

    Total amperage 28*0.45=12.6 A

    In this example one 16 A socket is sufficient.

    Hope this helps.

    I don't know what socket you are referring to with 4 pin plug. Most lamp sockets have two contacts not 4 unless it is a 6 way lamp with three filaments?
