Been doing a little more poking around ...

Here is a link to the Sylvania product catalog. We are using the M400/Multi-kit .. page 49

Now here is a link to the Intermatic K4236C photocell we are using that is switching the 110 leg of the 220V going to the lights.

Assuming the photocell is wired correctly (still need to check), can anyone see a problem with using the PEC with the M400 multikits (remember I have 4 fixtures connected)? It looks like to me we are pushing the current limit of the PEC. But seems like that would blow the PEC before having problems with the ballasts or lamps.
