Selection will follow the same procedure as any other selection:
- Write a specification:
- Primary rating.
- Secondary rating.
- Primary conductor size and shape.
- Maximum size.
- Insulation voltage rating.
- Electrical standards compliance (CE, UL, etc.)
- Environmental ratings.
- Warranty considerations.
- Availability and lead time.
- Business record of the vendor.
Then start shopping.
