MEP-006a convert from 240 to 480

[monkster]

I am trying to convert this genset from 240v to 480v. Is their anyway to do this? One of the plates has 358-480 60hz listed.

When up and running and per the tm to get the 60 Hz is by rpm's, I can dial in 120v or 240v. I am trying for 480v. (3 phase ) I am thinking that the circuit board just ahead of the (4) L's needs to be reconfigured. Any ideals ?

You'd need (at a minimum) to re-wire the voltage switchover board, changing the configuration from wye (240/416) to delta (240/480.)

Edit: I may be wrong on this... I don't think just a switch to delta will give 480 volts as each winding on the head is 120 (not 240 as I was bone headingly thinking!)

Thanks, I will mention that, i got a generator guy coming tomorrow and I will tell him that.

Switching it to 240/480 should be as easy as removing the 12 or so nuts on the voltage reconnection board that's under the front left access panel, move the card so the arrow points at 240/480 instead of 120/208 and crank the nuts back on. Of course make sure the generator is off and safetied in every way possible before touching that board.

The two choices are 120/208 and 240/416 (not 480). You can bump it up to close to 480 but that's pushing things a bit...

Oh, that makes sense. My mistake.
