rimcrazy, anything you're willing to share about your lightning protection install would be very welcome by me, either here or in a separate thread. Thanks.

Now what needs to be seen is the lighting protection I'm having put in. That is impressive. My property is quite high on the top of a hill and we get a lot of lighting especially now during monsoon season here in Az.







I will start a new thread and post some pictures. I'm having a professional install the protection. In short, he's burying a large plate where the rod comes down and then burying a large copper cable around the structure and is going to tie my steel pier (I have a very large 10' steel pier) to the ground. My building is a 10' HomeDome on a 10.5' x 13.5' x 7' structure. The lightening rod needs to be 29' in the air to provide proper protection. My son and I are constructing the pole right now to mount the rod.

Roscoe, thanks I figured there was at least one person who did that. If it was farther from the house, I'd definitely do solar and a good battery.

So guys, benefits of a trencher over a vibratory plow? Soil is semi rocky and obviously my lawn is in place. I'm thinking the plow is the better choice. Anyone have an opinion?

Yes a contractor is hooking it up

I am from canada so codes are different but I bought the direct bury 12g underground feeder from Home Depot in Tampa. It is direct bury but opted for conduit that I bought from Home Hardware for $50, solid piece of PVC with pull string. I went to a Habitat for Humanity resale outlet and bought a 15amp outdoor GFCI outlet and ran the electrical direct to my surge protected panel to a 15amp breaker. I also went to Harris and Roome (they sell electrical and all things cable related) and I bought 150' of direct burial Cat5e with a silicon core and I didn't use a conduit for it.

My run for electrical is approx, 105'.

Jeff,

My understanding was that you're not supposed to put direct burial cable (sheathed) in a conduit due to the potential for it to corrode quicker. That could be our NEC versus your own rules.

Anyways, electrican came out and quote me about 200 bucks to hook up a separate 20A service off my house's breaker with a disconnect (as required by code) in the shed. He didn't want to do the trenching, so I'm going to bury the cable for him (12").

I guess my only question now is whether a trencher is easier than a vibratory plow. Anyone have any advice on that?

Thanks,
Chris

I'm staying with the extension chord and my wireless router. It take me about 20 seconds more than simply walking to the Pod. Too many regulations (thus $$$) to think about hardwiring. So far the router and the extension chord have not been problematic, but then I do my observing in the observatory. It might be different if I wanted to control all from the house.

Ed,

I've actually been relatively surprised at how reasonable it is to run a 120V/20A circuit out to my shed. The distance involved is 80' and the total cost right now (with me doing some of the grunt work) is going to be about 400 bucks. From a safety standpoint (we have sprinklers and little kids) along with a reliability stand point, I think the cost is marginal to the overall cost of the shed.

Of course, it all depends on circumstances.

I've gone the solar route using Harbor Freight panels. Saves a whole lotta trouble.

http://www.harborfreight.com/solar-panel-kit-45-watt-68751.html

with their weekly coupons, can be had for around $130

I too have a similar job for a work shed not far from my Skyshedpod. Trenching is likely the way I will go. Here in Ontario I have to use one of these methods.

Current Ontario burial cable fact sheet

Sub rule 3 Depending on the conduit, if it is not rated as electrical raceway then burial cable is required. Likely that is the same across Canada as the codes are usually national with provincial addons.

Pierre,

Direct burial wasn't as bad. I skipped the vibratory plow and trencher... turned out to be the smart move too. Our soil is so rocky around here I would've got in serious trouble and it would doubled the cost of this project.

So I've got the wire buried (along with Cat5E direct burial). The guy is coming out on Tuesday to hook it up.

Harbor Freight panels are now way overpriced for what you get. Can get a good polycrystalline panel for the same price, one with a higher output.
