What is typically the electrician's responsibility in most central heating installations?

In most central heating installations, the electrician's responsibility includes performing the rough-in wiring. This involves laying out and installing the electrical wiring, making certain that it meets local codes and is properly configured to connect with the heating system components. The rough-in stage is crucial because it establishes the infrastructure that will support the system's operation.

During this phase, electricians ensure that the wiring is appropriately placed to allow for future connections of thermostats, controls, and the heating units themselves. Proper rough-in wiring sets the foundation for an efficient and safe heating system, allowing for effective electrical connections when the installation is completed. This task is a key part of the electrician's role in making sure that the heating system will operate effectively once fully installed and wired.

While the other responsibilities mentioned, such as completing final connections, insulating heating elements, or testing the system, may be part of the broader installation process, they typically fall outside the primary responsibilities assigned to electricians during the initial rough-in phase.
