I would like to learn more about how you used the “rim form board”. Is it only on the exterior of before the pour? Then when it is removed, it creates a key way for the next level of wall along the outside of the slab? That is ingenious but not sure how much an inch and a half x three and a half keyway will really help in outer edge concrete to stabilize the next level of wall??? More details would be greatly appreciated. It sounds like a nice touch even if it doesn’t do much. Every little bit helps. Thank.
Yes only on the exterior of the wall. I also change from using the 8" wide wall for the Cellar below, and change to using a 6" wide wall for the above grade portion. The key is the thickness/ of 2x4. (11/2"). When the next concrete pour takes place the width of the key is not an issue as it is filled and the lower wall, the floor and the above grade wall becomes monolithic. I will be starting to post the above grade build of the Greenhouse some time in January. You will be able to see all that you want in those videos coming soon. Thanks for watching.
At about the 2 minute mark you mention you are using all DC power in the structure, but using a standard AC load center. I hope you found DC breakers to use in the AC load center because you absolutely can NOT use AC breakers with DC power. DC and AC breakers are completely different animals in how they 'extinguish spark' when breaking the circuit pathway. Please consult a electrician with solar DC experience if this is what you are planning. DC and AC behavior and characteristics are completely different.
I did not know that. I just finished reviewing on-line and you are correct. Thank you very much for bringing this to my attention. I have much experience with AC power. This is my first project using DC. I am thankful you let me know as it is still early on and I have now located a new panel / DIN mount style DC Circuit Breakers that will take the place of the AC panel. Thanks again. And Thanks for watching.
