CSA C22.2 No. 107.1 Clause 4.2.5.3 has an exception for the hole size
allowed over live parts, if the equipment is:
a.. 1.8 (or more) metres tall
b.. A UPS
Can anyone tell me why this exception applies only to UPS's, and not to
other power supplies?Arjen Dragt Compliance Engineering Inverpower Controls Ltd. email: [email protected] phone: (905) 639-4693 fax: (905) 639-2918
