The RM7830A must have an earth ground providing a connection between the subbase and the control panel or the equipment.
The earth ground wire must be capable of conducting the current to blow the 20A fuse in event of an internal short circuit. It is
recommended that the RM7830A have a low impedance ground connection to the equipment frame which, in turn, needs a low
impedance connection to earth ground. For a ground path to be low impedance at RF frequencies, the connection must be made
by minimum length conductors having maximum surface areas. Wide straps or brackets are preferred rather than leadwires. Be
careful to ensure that mechanically tightened joints along the ground path, such as pipe or conduit threads or surfaces held
together with fasteners, are free of nonconductive coatings and are protected against mating surface corrosion.

2000 VA maximum connected load to RM7830A Assembly.
3
Total load current, excluding Burner/Boiler Motor and Firing Rate Outputs cannot exceed 5A, 25A inrush.
4
Honeywell has tested this output at 9.8A at P.F. = 0.5, 58.8A inrush for 100,000 cycles (EN298 approval does not require
this test).
