I would just throw a pop-up canopy over it (ideally with a vent at the top). You can go and grab some sandbags to anchor it so it doesn't blow away.


This is what I do and it works perfectly.

It's been asked above, but: What outlet are you trying to connect with? Is this one 30A/240V outlet, or several 15A/120V outlets?

Makes a big difference - show a picture, or similar, or an actual number.

Yeah basically any off the shelf cord you buy should be fine.

If the cord has 30A plugs on it, the entire cord will be rated for 30A. That means minimum #10 AWG. I checked earlier and voltage drop over 100’ of #10 AWG, at 220V supply with a 30A load, was only like 2.75-3.0%. And that’s assuming you’re actually pulling a full 30A continuously, which in reality you won’t be.

In other words: if you can find a 100’ cord with the right plugs, go for it.

edit ----ooops, I see I just cross-posted with lostinbr above. So yea, what we said! :)

OK, then just match up the specific connector type (not all are the same, 3, 4 prong, etc) and look for an extension cord. Any reputable brand/supplier pre-made extension of 100' and those connectors will be of sufficient wire gauge.


Here's one, Home Depot $210 10 gauge, 4 conductor, 30A (is that your connector style?)

https://www.southwire.com/calculator-vdrop

Voltage drop will be limited to 2.86% or less with a 10 AWG copper conductor delivering a total of 30 amps on a 220 volt single phase system for a distance of 100 feet.


2.86% drop is fine, and you likely won't be pulling 30A all the time.

A 10x10 tent from academy would do just as good as that porch. that cord will not be cheap.

They sell a bunch of covers you can use


I got a 3/4" pvc and drilled a hole in the side.

Drive it into the ground.

Take a big umbrella a d drill a hole through the handle.

Line up the holes and run a bolt through it.

You can even zip tie the umbrella to the generator over the electronics.

Golf umbrella works. Then you can use the umbrella the rest of the year

Thank you, but explain this to me like I’m Biden - what does 8/3 mean? Assume 8 gauge but what’s the 3?


Firstly,

Secondly, you need 100’ of 8/4 SO cable. Two hots, neutral, and ground.
