    Can you guys help double check my work? sorry for using first grader schematics and drawing skills, but its the best i got so bear with me.

    Red line is live/hot wire that is daisy chained to all four.
    Green line is ground wire daisy chained to all four
    White line is neutral that goes from wall split into 8 going to "Slot A" in Relay
    Yellow Line is going from silver screw of all 8 receptacles to "Slot B" in Relay (broke break out fin on all neutral sides)

    So what do you think? Did I do this correctly? (look into the relay slots being correct and also if the power from wall is safe and correct and anything else i am unaware of. please :-D !!!!!! )

    The Mains Line Red wire should go to the Relay contacts, NOT the Neutral.
    Daisy chain the Neutral socket pins.
    BUT be aware of the total current loading on the mains wiring.

    If you switch the Neutral, it means that the sockets and whatever is plugged in, will be at mains potential.
