4.5 Transformer Close Coupled Connection
Close coupled transformer connections are another means of joining, but it involves joining the switchboard to a transformer
enclosure. This is typically done with a throat supplied on the switchboard that would mount to the side of the transformer’s
enclosure (see Figure 4.8 on the facing page ). The copper from the switchboard and the transformer are typically connected
via flexibar or braided copper rated for the application. Both normally connect using 0.5 in. or M12 hardware.
