Begin with the approved design
Use the project drawings, load schedules, specifications and bill of quantities as the starting point. Product selection should support the system design rather than replace it.
Describe each requirement clearly
Record product type, rating, quantity, installation environment and any required standard or consultant approval. Avoid relying on a model name alone.
Consider the complete installation
Protection, wiring, distribution, accessories and cable routing must work together. Coordinate related materials before ordering.
Ask for current documentation
Request available datasheets or catalogues and verify product suitability with the responsible qualified professional before installation.
Use this guide as general product-selection information. Confirm the final product against the project specification and current manufacturer documentation.
