Tank Mounting Structure For Dead Tank Circuit Breaker

The mounting structure of claim 65 in combination with the tank and flange, the flange having planar machined surfaces that engage a planar surface of the support structure when the tank is secured to the support structure in any of the three different positions.

A method of securing a tank of a dead tank circuit breaker to support structure, the tank having a flange extending from a body thereof, at least a pair of first bores extends into the flange in a first direction, at least a pair of second bores is provided with each second bore extending into the flange in a direction generally transverse with respect to an associated first bore so that each second bore communicates with the associated first bore, the support structure having bolt holes for receiving bolts, the method comprising the step of:

• placing the tank on the support structure such that each first bore of the pair of first bores is aligned with an associated bolt hole in the support structure,
• placing a pin in each of the second bores of the pair of second bores, each pin having a threaded pin bore that aligns axially with the associated first bore, and
• inserting a bolt through each associated bolt hole of the support structure, into an associated first bore and into threaded engagement with the threaded pin bore of an associated pin so as to secure the tank to the support structure.
