Sorry maybe I'm a bit high
I was wanting to replace the breaker on the Helios 10 with a 20a, and plug that into the 40a dryer outlet. That way, when the lights are on they wont get more than 20a, but on the off occasion, I can just unplug the helios and use the dryer at its normal 40a.
I'm too noob at electrical work or don't understand the Helios 10 completely (limited docs available) but to me I was seeing it as kind of a "plug in circuit extension" or a plug in 1 circuit sub panel (of sorts) with outlets?
