(d) Clause 10-all dc machines in IEC frame size 90 and larger;

(e) Clause 11-portable and standby generators; and

(f) Clause 12-inverter-duty variable speed ac machines.

This Standard provides basic requirements for machines and does not exclude any additional requirements given in other Standards of the Canadian Electrical Code, Part I/.
