Question:4 p5 l; _# v& b* M2 k$ r& `7 ?
In clause 20.7.4 of IEC 60598-2-20, it is mentioned that only 4.11.4 and 4.11.5 of clause 4.11 apply for1 P2 l. C1 b5 _+ f+ N
electrical connections and current carrying parts. Sub-clause 4.11.1 (contact pressure through insulating
" }. y2 m# [7 y5 m8 B8 ^material) does not apply. In a rope light connecting system we often have connections with pins that are6 P* U9 T" N$ }6 T( J4 s
stuck axially into the bare wires after cutting the lighting tube. This is contact pressure through insulating! {7 [$ F& g0 e# `: a
material. With about 16 W/m and a length until 100 m we can have a current more than 6 A at the

our opinion, to the connection to the lamp only (e.g. connection to Edison lampholders with insulating

the matter.
