Could someone help me understand the differences between cable protection conduits such as MRF-804A-C1-S20E and MRF-804B-C1-S20C in electrical engineering plans? This post was last edited by btlhrdb2008 on 2009-4-23 21:02.]

S20E and S20C refer to steel pipes of DN20; E denotes exposed installation while C denotes concealed installation. I’m not familiar with the meanings of the other terms

Thank you, now I understand. It’s the inability to distinguish between explicit and implicit pairing. One more question: which word are C and E abbreviations for?

C stands for concealed (hidden), and E stands for exposed (visible).

-The symbol before C should be the device tag. -C represents the power cable
