Direct answer
What this result means
Calculate edge-to-edge gap between two circular entries from diameters and centre distance. The relationship g = P − (D1 + D2) / 2 ties first entry diameter, second entry diameter and centre distance directly to the reported result. Entries are circular and their centres lie on one line. Treat the value as a transparent preliminary calculation, then compare it with the actual cable-entry assembly and current product documentation.
Formula & theory
Make the assumptions visible.
g = P − (D1 + D2) / 2 defines the calculation shown here. Entries are circular and their centres lie on one line. Keep the entered units with the result so another reviewer can reproduce the method.

Variables
Use sequence
From measurement to review
- Confirm first entry diameter and second entry diameter from a controlled drawing, measurement or project document.
- Apply g = P − (D1 + D2) / 2 with consistent units and keep the entered values beside the result.
- Use edge-to-edge gap only after checking hex envelopes, tool access, sealing washers, plate strength and installation tolerances.
Limits
What this calculation does not confirm
- Entries are circular and their centres lie on one line.
- Inputs describe one defined operating or measurement condition and use mutually consistent units.
- The result does not by itself confirm product suitability, standards compliance, ingress performance or installation approval.
