[Dsg-rich] RICH Compressor in EEL

[Jason Willoughby]

Walt, 

The current setup is a 208 100A panel. This will not provide adequate power to run both compressors at the same time. The options to remedy this are as follows. 

Option 1: If both need to run at the same time, upgrade the existing 30kVA transformer to a 75kVA unit, and replace the existing 100A panel with a 225A panel. 

Option 2: If both need to run at the same time, install new 30kVA transformer and new 100A panel (will need additional floor space) 

Option 3: If only 1 needs to run at a time, install a new DPDT switch by the compressors and utilize the existing 70A feed to run either compressor. This switch runs about $950.

I'll let Jason weigh in on this, but, I believe that, if the Bertha 
is disconnected, this is no longer a hot system and you should 
be able to remove the cables - if you know how to do that work.
