After encountering several cg's last year with less than optimal voltage capabilities, we bit the bullet and installed a Hughes Auto Former Voltage booster. Of those that have done the same, do you have yours wired
where it is constantly connected or only connect it when low voltage is noticed?

I mounted mine in the compartment with the shore power cable and generator outlet and used the Hughes installation kit. That way, it's easy to reconfigure. I can disconnect it, or leave it permanently connected if I want to.

One good reason to do it that way, is sometimes the relay contacts in the autoformer get stuck together while boosting.

Then, when pedestal power returns to normal, the voltage out of the Hughes will be too high.

That happened to me last trip.I just took the Hughes unit out of the circuit until I could fix it.

My Hughes is mounted in the basement and wire with the disconnect kit. It is wired ahead of our Progressive Ind hard wired EMS.

We leave ours hooked up all the time. I do have a Progressive Dynamics voltage/amp meter visible in a cabinet above the driver's seat so if the voltage were to go high (130v +) as I have read, I can quickly disconnect from the auto former. Ours show 124v +- when plugged in under light load and has on occasion dropped to 116-117v when in a full cg. For what these thinks cost, sounds right to leave it plugged in continuously and only unplug if it malfunctions.
