Support Paralleled Generators Connected to Switchboard
DM does not currently support more than one source on the Normal side of an ATS or the EM side of ATS, however larger I-2, I-3 occupancies generally have paralleled generators connected to a switchboard. This feature would avoid cumbersome work arounds.

This would prove very helpful. Especially with companies such as Russelectric and ASCO being able to incorporate ATSs and MTSs within paralleling switchgear and switchboards.

This might be more useful if you could have more than one source for a BUS device. We often model multi-section switchboards as separate pieces of equipment, with the first section as either a gutter (if it's MLO) or as an enclosed breaker (for a main). Having a BUS that allowed multiple inputs would make either of these possible.
Similarly, we recently had a project with an existing MDP with a main but no capacity. We needed to add a second MDP, but the power utility would not strike the building more than once and the existing transformer was the largest one they normally stock. The solution was to place a second transformer in parallel, join them in a junction enclosure, then bring in separate service entrances for the two MDPs. his would again be easier to model if we had a bus gutter that allowed multiple inputs as well as outputs.
