Image: Circuits numbered using the UK ways and phase convention (left), and wires tagged using this circuit naming scheme. Further, the phases aren’t referred to as A, B, and C, but rather as L1, L2, and 元. Ways is the grouping of three circuits spanning the three phases.

However, in the UK, circuits are identified by ‘ways’ and phase. For example, in 3-phase branch circuit panels, typically, circuits 1 & 2 are on Phase A, 3 & 4 are on Phase B, and 5 & 6 are on Phase C… then the sequence repeats. The area we tackled within Revit that historically has been very US-focused is the way circuits are numbered. Ease of Use includes improvements that we hope benefit your day-to-day interaction with the software.This logic is what allows Revit to properly physically and analytically represent an electrical system. An example of an improvement to distribution system logic in the 2020 release was the incorporation of feed through lugs.
