Staying within scope of the design

One important feature with the 61439 series of standards is that the complete assembly is verified to comply. If you start to make additions or alterations to the design, then the person doing this works takes on the responsibility for this altered design and needs to ensure the updated assembly is verified to comply with the 61439 standard - the original manufacturer is no longer responsible.

With the Concept Panelboard, range there are several additions or alterations that can be completed to a catalogued configuration, so that the assembly still complies to the standard.
