Good to Know
What are the differences between the PX100 and other Intermatic PX models?
The PX100 is a 100-watt unit featuring a corrosion-resistant beige steel enclosure and a 1-year limited warranty. For a 100-watt unit with a stainless steel enclosure and a 10-year warranty, consider the PX100S. Other models like the PX50, PX300, and PX600 offer varying wattage capacities.
Can I install this transformer myself?
No, this electrical equipment must be installed by a qualified electrician. Installation must strictly adhere to the National Electrical Code (NEC, Article 680, specifically 680.21(b) and 680-24(b)), Canadian Electrical Code (CEC, Section 68), and all local code requirements. Improper installation poses a significant risk of electrical shock or fire.
