FAQ & Support

Will the approval documents match the exact cable you quote?

Where a certificate, test report or DoP is part of the approval package, we match it to the quoted cable construction and the applicable scope. A document for one version is not treated as approval for another simply because the model name is similar.

What CPR evidence is available for H1Z2Z2-K Eca, Dca and Cca?

Eca is supported by the applicable test report. Dca and Cca are supported by the corresponding CPR certificate and Declaration of Performance. The CPR class, construction and size being supplied must fall within the scope of the supporting documents.

Does the same H1Z2Z2-K CPR documentation cover Twin, PV Extension and rodent-resistant versions?

Not automatically. Twin constructions, connectorised extensions and modified constructions such as nylon barrier or steel-wire armour have to be checked against the scope of the applicable documents. For a PV extension lead, CPR evidence for the base cable does not by itself classify the complete connectorised assembly.

Do you currently have an EPD for these cables?

An EPD is not part of the standard documentation currently supplied with the product range. If an EPD is mandatory for project approval, tell us the exact product and required schedule before quotation so that feasibility and lead time can be confirmed separately.
