The MAS™ system uses a conduit system that is embedded in the foundation. The MAS-1300™ has a total of 5 duplex boxes per side, of which 2 of these home run to the electrical panel area. Thus you end up with 20 duplex boxes, and 8 home runs. This allows great flexibility for line voltage or low voltage applications. The final interior wiring connects to such boxes. If spray foam is going to be used, then Romex can be be “hot glued” to the walls when installing additional duplex outlets, and then covered by the foam. The The MAS-570™ works in a similar manner however, it has only 3 duplex boxes and 1 home per side (total of 12 duplex boxes and 4 home runs).
Note: The conduit system is very inexpensive as it is used to create a void in the concrete. The concrete is what is actually protecting the final wiring and thus this inexpensive conduit does not require any type of rating.
