What does “factory pre-connected cold leads” mean for the MI Cozy Heat cable?

Cold leads are the non-heating sections of cable that connect the heating element to the electrical panel. Standard MI cables require cold leads to be spliced on-site — adding labor time and introducing a potential failure point at the splice. Cozy Heat’s MI cable ships with cold leads already connected at both ends from the factory. The installer routes the cold leads from the heating zone to the panel and terminates them — no specialized splicing tools or additional field connections required.
