The directory

Details make the difference.

Find a model. Check the configuration.
Take the evidence with you.

A registry listing is a starting point. CEC inclusion is not nationwide installation approval. Confirm the exact model and configuration with your utility and local authority.

The evidence matters

A clear view.
An informed decision.

The original record, always.

Every CEC record leads back to its source workbook and check date. Archived files preserve the evidence even when a live list changes.

Follow the evidence

Context before conclusions.

A listing is one part of the picture. Model variants, utility requirements and installation conditions deserve the same attention.
