How about creating venting along the top portion of the wall with a plywood or foam enclosure along the interior. Below is a poor edit of your original image, but should make the point. I've seen this done before to retrofit buildings without soffits to add venting. I think they even make...
Simple motor hp calculation (240*15)/746 comes to 4.8 hp. I have no problem hardwiring it in, though for the last 13 years, I’ve ignorantly been running it with a 240v/20a plug, with no issues.
Thanks for the information.
I’m here to learn.
I've exhausted the Google machine and the GJ search function, with no real answers to my particular conundrum.
I am in the process of purchasing a home that will allow me to build an additional attached garage that will be my dedicated auto workshop.
Issue: I will (obviously) need dedicated...
I regularly prove the adage of "you learn something new everyday".
I could not find any data on the defrost mode for my system.
I will probably not be welding at max current when the AH comes on.
The 90A would come into the breaker box and I would have a 60A, a 20A and a 30A breaker for each...
You are not getting in my stuff at all. I absolutely appreciate the knowledge! I will look into the issues you brought up. It does have 2 inputs, a 60A and 30A feed. I was totally unaware of the defrost mode.
I'm confused, if it has a 60A breaker feeding it, how could it require 70A? The HP is a smaller unit for about 1200sf of space. I'll have to check the size, but at less than 10000kva it isn't big, right?
I accept that I may have to secure the HP when running these other loads, but that will be...
I understand using the HP feed is not ideal.
I just thought that since they went overkill on the feed that I could use the extra ampacity of the wire to supply power to some other infrequently used items. All the 120v is supplied by the main since this is an attached garage.
Since this is...
I appreciate the feedback.
Load Calculation:
Feed: 21600VA
HP: 9600VA (per spec sheet on unit)
Welder: 6000VA
Comp: 3600VA
Total: 19200VA
Based on load calc, the 90A feed will support the loads.
This is not a permanent solution, just a measure to get my shop going. I will run a...
If the circuits are all 220V then there is no neutral, just two 120v legs and a ground correct? If the feeder ground is grounded at the main and the circuits are grounded at the sub panel and the box grounded, isn't that the same as bonded conduit?
