FAQ

Questions buyers usually ask

What fault rating should be specified?

The short-time withstand and breaking ratings must be selected from the calculated fault level at the switchboard, including future network configuration and source contribution.

Which standard should be stated in the RFQ?

Use the project or utility standard stated in the specification. Where it is not defined, send the destination, system voltage and application so the appropriate IEC or ANSI/IEEE basis can be proposed.

Are guaranteed values the same as the website values?

No. Website values are selection guidance. Guaranteed performance is stated in the approved technical data sheet and commercial offer.

What information helps Apex respond faster?

A single-line diagram, load data, voltage ratio, capacity, quantity, installation conditions, destination and required delivery date provide the best starting point.
