Intellitec 15 Amp Transfer Relay Delay 00-00568-000 Obsolete / No Longer Available, However the 30 Amp is still available while supplies last: 00-00638-000 (LINK)
Description: Intellitec’s Transfer Relay Delays are designed to automatically transfer a 120 VAC load, between two power sources, such as generator and shore power. The units are responsive to one of its inputs. If power is applied to that input, after a 15 second delay, the load will be switched to that input. This input is typically fed from the generator of an RV, to transfer the load to the generator from shore power, when the generator is running.
