use of welding cable for electrical service

My electricians have in the past used 2/0 (or other sizes to meet current requirements) essex excellene +105C -50C 600v welding cable for short runs, say from a circuit breaker to a contactor through nipples or in short gutter runs, especially when flexibility is helpful or guarantees that the insulation won't be damaged while making the run. I maintain this is not permitted since it is "cable" and not listed in the tables in article 310. Any input?

Mink, the term welder cable can be both explicit and generic. You need to look on the side of the cable you are using. Then tell us the initials on the side such as RH RHH etc. Then we can better tell you if this wiring is allowed for use as a building wiring method. If it says welder cable on the side of that cable then it is an explicit listed and labled cable for a specific use and is not allowed for a building wiring method as declared in its testing lab listing a labeling.
