Overhead electrical lines exceeding AC 1 kV - National Normative Aspects (NNA) for Poland (based on EN 50341-1:2012) subscription-only1. Scope 1. 1 General PL. 1 Scope of application This NNA determines the requirements which shall be fulfilled while designing and constructing of new overhead lines with nominal system voltages exceeding 1 kV AC. The scope of use of this NNA for temporary lines shall be determined by the Project Specification. For modernisations, reconstructions and refurbishments of the existing lines, the scope and the requirement to comply with PNEN503411,

Although this code of practice is not intended to include industrial type powered doors and powered turnstiles

It is also applicable to breakers intended to work downwards to break hard materials (concrete

Laboratory quality assurance

This helps to seal the cracks

as well as the aggregation of information by third-party suppliers
