About the Marley 5814-0003-001
The 5814-0003-001 is an original-equipment control transformer for Marley, Qmark and Berko electric heaters. It takes a 277-volt supply on the primary side and steps it down to 24 volts on the secondary.
Marley sells versions of this transformer for other supply voltages under nearby numbers: 5814-0003-000 for 208/240V primary and 5814-0003-002 for 480V primary, both with 24V secondaries. Match the primary voltage to your heater's supply and check your model against the compatible-models list on this page.
Installation Tips
