Selden Mast - Running Cables
From The Selden Manual (assume you have a Selden):-------------------- quote ----------------------------All Seldén furling mast extrusions are fitted with a cable conduit.On keel-stepped masts this goes uninterrupted through to the foot.The mast is provided with a messenger line from the factory.Thread a new messenger line at the same time as you run throughany new cables. This will ease any future, further, cable running.If an existing cable should prevent a new cable being run it should be extracted, but attach a new messenger to the cable first, to take its place in the conduit. That messenger can then be used to draw two or more cables through the conduit – but do not forget to draw a replacement messenger through at the same time.Cables are fed into the conduit through a hole in the mast wall by the head box. Cables should be over-length to allow subsequentremoval of the head box without electrically disconnectingmasthead installations.Cable exits are located in the mast heel casting.------------------- unquote --------------------------------The above may be of some help - provided there is a messenger line in the mast. Otherwise you will need to feed a new messenger line through the conduit in the mast. You can download the manual from Selden's website.Good luck
