Installation of Bus-structure Equipment.—Insulators for supportingbuses and other live parts should be as compact as possible, and should bebolted or clamped to the wall or slab. They should not be cemented intothe wall or slab, since this construction causes considerable disturbance inoperation when it becomes necessary to exchange an insulator. Whenclamping bus insulators, the clamp should be made in two parts to avoidthe necessity of lifting the bus when exchanging an insulator. For boltingdown insulator pins, slots can be conveniently provided in the insulatorpin instead of bolt holes. Oil-switch cell doors may be made either of asbestos wood or sh^et iron,with angle or channel framing. It is advisable to suspend the door from * Electrical World, Jan. 15, 1916.—The Design of Power Station and Substation BusStructures, by M. M.
