How long does it take to connect a Reliance Pro/Tran® transfer switch?
About an hour by a qualified electrician familiar with residential wiring electrical codes. If installed with a power inlet box, the installation could take slightly longer. Since each unit is pre-wired, the installer simply needs to determine which circuits will be needed during an outage, wire each set of wires in the transfer switch to those circuits, install the neutral and the ground, and test the installation under load.
