Generac 5621 – Frequently Asked Questions
1) What does a Generac 5621 auxiliary contact kit actually do in a transfer switch?
The 5621 auxiliary contact gives the transfer switch a way to interrupt a low-voltage control wire when the switch moves to generator power. Breaking that signal keeps the appliance from turning on, so one load is effectively locked out while the generator is carrying the house.
2) I have two central AC units and electric heat on a standby generator that can't carry everything. Will this help?
That is the situation the 5621 is sold for. Homes with high electrical demand, like electric heaters or multiple central air units, use the auxiliary contact to shed one of those loads during generator operation so the rest of the panel stays within the generator's capability.
3) How many loads can one Generac 5621 contact kit lock out?
One. Each 5621 auxiliary contact handles a single load. If you need to shed two separate loads, such as two condensing units on different control circuits, you need one kit per load.
4) Is the Generac 5621 a load shed module that switches the appliance's power feed?
No. The 5621 interrupts a control wire, not the line-voltage feed to the appliance. It breaks the signal that tells the equipment to start, so the appliance stays off while the contact is open. If you need to open the actual power conductors to a load, this is not that part.
5) Does the Generac 5621 come with the mounting hardware or do I need to supply screws?
Screws and washers are included with the 5621 auxiliary contact. What is not supplied is the control wiring between the contact and the appliance's control circuit, so plan on that being field-run.
6) Where is the Generac 5621 contact kit made?
The 5621 auxiliary transfer switch contact is manufactured in the United States, which matters on jobs with domestic sourcing requirements.
7) Does the Generac 5621 carry a California Prop 65 warning or any shipping restrictions?
Neither. The 5621 contact kit is not flagged for chemicals causing birth defects under California Prop 65, and it carries no shipping restrictions. Assembled weight is 1 lb.
