Mar 25, 2017 · I'm trying to figure out what my spacing between insulator supports is supposed to be for low and medium voltage applications. The only applicable document I could find that gave me actual spacing values was UL 891 Table SB3.1 where it breaks the distances down depending on bus configuration (edge to edge vs face to face) but UL 891 is only for "dead-front switchboards".

If you are developing a new product, at first you have to size the busbar support and spacing based on calculation and then test it. I don't think there is a single rule that applies to both LV and MV equipment. IEC 610865-1 and -2 provide a guidance to the calculation. Hope this helps.

Instructions around how to install the busbar support are the responsibility of the original manufacturer of the switchgear system and issues such as the spacing of the busbar supports are determined by the manufacturer’s testing. These distances are governed by the fault level and the size of the copper bar.
