I have a customer with a 100W HPS fixture on an outbuilding. The fixture is photoeye controlled. Almost everytime that a large load starts in the house (A/C, sewage ejector pump, ect.), the light shuts off and eventually comes back on.
The outbuilding and house are both on seperate loadcenters and feed from the same main panel at the meter. It appears to me that this is caused by voltage drop. Correct?? I even switch the fixture circuit to the opposite phase and it still does it. Could this be simply a photoeye problem, or utility service voltage drop???? Any suggestions?
