rowd, check out hiialeah meter.com they have wiring diagrams for all types of meter sockets.if i'm not wrong you would put the hot on the left hand line stab run neutral through middle,then run a jumper to the right hand stab. sounds like the power compny doesn't like the idea of providing a form 1S meter that is designed for this application.this meter is usually rated 100cl 120 volt two wire.most meters that the power company uses for residental service are form 2S class 200 240 volt 3 wire. these reguire the 2 hot legs.why do they want to meter each 400 watt seperate? why not use a sub meter if it's to bill each customer, & use one main house meter.hialeah & several others can provide these for you, unless there not allowed in your area.
