Ok rad.  How do I run my macrotech I-series at 240v?   Do I get any benefit out of that?  My rack as follows:

1x ma9000i
1x ma12000i
1x Furman p1800ar
1x behringer Inuke 46000
1x Midas DL32 / m32

I think all/most could run at 240, but this rig gets used most of the time off power at venue.  Generator happens maybe 12x/year.  I want to keep this EASY and not move things in and out of 240/120.

So I THINK I want to keep 120 across the board.

Bonus points for anyone who can link me to a distro type unit thatíll do what I need , for under $400-500.

In my area, I can easily (and cheaply) rent a 50A 120/240v "spider box" at a rental business.  If you have that available as an option in your area, your could make a special cable that has a L14-30 male plug and a California 50A female connector on the other end. The L14-30 would plug in to your generator, and the other end into the rented spider box.  That is a legal usage (30A plug in, 59A connector out). By analogy, you can pour a full 3 gallon bucket into a 5 gallon bucket, but not the other way around.

The adapter cord (with a rented spider box) is your cheapest option (at least in the short to medium term).

Chris Hindle's response give the gist of what wet stacking is. Essentially, you will foul a diesel engine by running it below minimum operating temp. It's detrimental to performance and longevity. Preventing wet stacking in a prime power situation requires some planning and maybe a load bank to help get the motor up to temperature. I'm far from being an expert on the subject.

As an example, when I was working overseas, our operation was on diesel prime power. Maintenance had issues with users turning off all the lights and HVAC to "save on electricity" but turning everything off would drop the load enough to wet stack the 1.5MW gensets in use. The solution was to leave everything running 24/7, including office lights and HVAC. Sounds insane but kept everything running smoothly once the solution was implemented.



Hey Tim H, what is ďwet stackingĒ?
I am not familiar with that term.

These arenít rack mount, but definitely fit the budget. Search for temp power distribution boxes. May not be ideal....thatís for you to decide. Northern Tool also carries some products for this use.

I use the LEX rack mount with a 50A plug inlet and 6 20AMP branch circuits, put half the load on A side and the other half on B side of the buss.

Guys - next step- suggest to me a basic sister solution. I need a California style 50a/240v inlet broken down to 4x 15a 120v circuits.

Racked or standalone box.
