Thank you all once again for your thorough input! I am forwarding all to my husband who is currently at work. He will get back to this discussion later. To me, it seems like our current panel is already pushed to the limit? May need to bring in a whole new line from the pole and drop down? Please excuse my lack of knowledge on the correct wording. Thank you for the complement on the set up. So much planning and work went into it, sadly without knowledge of kiln failure and having to replace wiring in the kiln. Also, we didn’t know how 30 amps is now very limited. I will post more detailed photos of our panel. Don’t know if the marking is completely updated. The other electrical to the kilnhouse are two plugins and one light. Coming in through the same as the 220 for the kiln. I believe the line is at least 5” buried.
