We currently rent our load banks for generator testing. We have come to the point where we rent so often that if would pay for us to have our own. I am looking to build a 250kva bank and am looking for wiring diagrams.
There is a lot more to a load bank then wiring diagrams.
There are any number of companies that make them, including the one I work for.
There are lots of issues that need to be addressed.
1) water or air cooled?
2) resistive, inductive, capacitive, or combo?
3) voltage
4) load steps
5) do you need automatic sequencing of loads?
6) single phase, 3 phase, or combo?
7) safety issues
8) monitoring and data collection
