What does “pre-connected cold leads from the factory” mean?

Cold leads are the non-heating cable sections that connect the heating element to the electrical panel. On standard MI cables, cold leads must be spliced onto the heating element on-site during installation — a process that requires special tools, adds labor time, and introduces a potential failure point at the splice. Hott-Wire’s MI cable comes with cold leads pre-connected at the factory, eliminating field splicing entirely. The installer simply routes the cold leads from the heating zone to the panel and terminates them — a straightforward connection with no specialized splicing equipment required.
