Bundle Box??

[Arc Blast]

Read a post in the troubleman's forum, lineman refered to a LV bundle box going phase to phase. Asked all the lineman at work and none of them had heard that term. Is that australian for transformer?

secondary blocks. Got a hole in them you stuff the wire in and then tighten the connection with an allen wrench type tool. Some call them Kansas City doghouses. Square connector with different sizes and number of holes etc.

Yeah I bleve Door is right. Some outfits use em for connections on larger wire sizes like 500. Its an aluminum block with holes for the wire and threaded set screws to tighten it down.Theres a rubber cover that slips over the entire block for insulation purposes. I bleve the original application was intended for Urd connections in a pedestal, and people kinda started usin em at weatherheads and anywhere else they could puttem. They also make em to put in transformer bushings allowing you to make up several services to a pot without using any other connections, These have a solid bar at one end and just slide right thru the lugs on a xfmr.

Sounds like hes reffering to the connectors used on lay cable.. Lay cable is alot like triplex except it has a lashing wire around the conductors and is used to replace open wire secondaries. The connectors are basically wedged between the conductors where it seperates them and allows you to tighten them down to the connector. The connectors have two bars inside for service connections that are covered and made up with allen screws..

Theres also the large alluminum service blocks we used to use that were described.. The are great on large parrallel services but on single runs we use fargo clamps or H taps.

Then you have the waterproof URD molds (They arent really water proof though.) Those have been used everywhere around here by the contractors both above and underground.
