received lighting fixtures from owner requiring "150 degree wiring" One type terminates in round hub at arm swivel and since it's not adjacent to ballast; I figure we can use 90 degree cord (no conduit entry). The other fixture will require wiring in ballast compartment and I am not aware of any cord that is rated 150 degree and is also sunlight resistant. Where do I find temp ratings and amperage ratings for flexible cords?
