Provision is made in the control cubicle wiring for connections to be made to a remote condition monitoring unit to be fitted either at the time of installation or at a later date. A space envelope is provided on the cubicle enclosure gear plate for the unit to be fitted.

Due to the nature of the GrayBar control cubicle, real remote condition monitoring is possible. Rather than only measuring the outgoing supply to the transformers, such as is the case with constant wattage; the current to each heater can be monitored. Complex data, such as the differences in temperature across each site, could be easily compiled
