Cable size should include a growth factor of what percentage?

Planning for future expansion is essential when sizing cabling. You don’t just match today’s load; you add a growth allowance so the system can handle increased demand as devices, users, and applications grow. The typical range used in practice is about 15–20%. This level provides a practical margin to accommodate growth without immediately incurring the extra cost and space that a larger allowance would require. If the growth factor were too small, say 5–10%, you risk needing upgrades or rework sooner as capacity is consumed. If it’s too large, such as 25–40%, you’ll pay for more capacity than you’re likely to use, which wastes material, space, and budget. So, applying a 15–20% growth factor strikes a balance between readiness for expansion and prudent upfront investment.
