What are split boards?

This article shows how to use Pirform to report all the RCD equipment for boards with multiple RCDs, also known as "split boards".

Here's an example of a dual board that you can pick up from our friends at City Electrical Factors in the UK:

What is the problem?

To do that, click on Show Remarks in the ribbon, select the first circuit, then record which circuits that the RCD protects:

Repeat this for the second RCD and Pirform will then report those in the relevant section in the PDF:
