Electrically, it is best to place a panel mounted shunt in the ground or return line near the voltage source, as this helps to limit the voltage potential between the shunt and adjoining grounded panels. In a majority of busbar applications the shunt should be placed on the ground or return conductors to minimize shock hazards. Precautions must be taken to ensure proper creepage and clearance to adjoining conductors and panels to allow for the system voltage. Mechanically, the panel mounted shunts should be placed so that the resistive elements are vertical. An easy way to remember this is that the shunt should be mounted to a wall (or panel) and not the base or top of an enclosure. Busbar shunts should be bolted to the busbars with a thin film of conductive grease on the mating surfaces and the bolts firmly torqued to specification. Large, high current shunts will benefit from additional insulated support mechanisms to relieve stress to the manganin/terminal solder joints. In addition, it might be necessary to allow for some thermal expansion via the use of flexible interconnects.
