And since it is the single point ground on the A427 load bank, I keep the bonding strap in place connected on the generator. (Ground + Neutral)
Note: When done using the load bank, keep the generator on and load bank on for a few minutes after with no load. Need to finish cooling down the panels.

Go back and look at the pictures for a 1 phase 120/240 wiring connection. You also use the 8 inch long copper strap to connect the 3 upper lugs. It is stored inside the cage next to the lugs.

Howdy,
If you're asking, maybe it's not for you. Really tough to find them out there. I would suggest maybe a old electric stove. Others have found a electric shop heater works too..
Howdy,
The overload trip is a time vs amount vs percent power type of trip. The units will trip on a overload. The unit is designed to keep chugging, and then trip when finally saying it is a over voltage fault. Will the unit stay running at a 105% power usage. Probably yes. Will it stay...
Howdy,
I have listed to what I have pushed each style of MEP too. No, I am not abusing them. The government specs them to be load tested to a overage for a certain amout of time.
Howdy,
Here is my MEP-803A generator load bank log run.
The hardest, and hottest portion was of course the 133% loading. The oil thins out and got down to 30 psi

Howdy,
Loaded MEP-803A with a surplus load bank. I warm the 803 up. I then start stepping through loads.
3kw, then 6kw, then 9 kw, then 12kw, then 12kw+3kw, then I start adding the variable load a little more than half way. Probably adding another 1.75kw to get it up to 133%. I then back off and...
Howdy,
Further back in the thread is a hard loading of a MEP-803A. Also is a posting of the way the gauges were looking at each of the loads.
MEP-803A 3kw to 16kw loads.
I was pushing 67.2 amps per leg at the end.
Howdy,
I think it still was around the same contract time. Kinda like a Libby, or Fermont.
Eitherway, it really makes testing and working a generator easier. :)
Howdy,
Every generator that is started for non use, gets put on the load bank. Any generator will be loaded to 80% and run at least 2 hours.
This might be monthly, or every other month, or 2 months.
A NOCO G7200 with a slave port connector is moved around the units to maintain the batteries.
Howdy,
The new AMMPS have built in parallel ability. It also make it possible to load bank more than 1 to many units using parallel loading. Or, in real life, 2 x 5kw units working as a 10kw unit. Or 3 x 5kw units working as a 15kw unit.:cool:
Howdy,

A new addition being worked on the load bank. I really like that whatever load is applied, the unit holds it right at 60Hz, and 120 volts on each leg.
Howdy,
I use the load bank regularly. I can vary the loads easily. Anytime I start up a generator, I place a load on it.
A load bank is just that. A method to put a electrical load on a generator. You can find all kinds of things used as load banks. Some members have used water heater probes...
Howdy,
For those interested, and possibly on the west coast. A member here has some Essex A427 load banks he is selling. Gilroy, California
