That's why, for one of the mountain-top comm sites that we designed for a desert site out in the middle of nowhere, we specified - ready for this - 900 Kcmil conductors (*) for a 120/208V 400A feeder because the power company located the CSED (Customer Service Entrance Device) i.e. meter and main breaker installation - at a point down the hill that they could reach in any weather. (* Visualize copper-filled garden hose. 3 sizes over minimum code (4/0 AWG) to minimize voltage drop and conductor heating.) 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 From a Clearing in the Silicon Forest Beaverton (Washington County) Oregon ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
