The 20001534 Heater Jacket Power Kit is designed for 200-240 VAC Series 49 heaters. The power kit includes an 8 foot 240 VAC power cord and Series 49 power junction block. The junction block supplies power to a chain of heater jackets and provides for communications pass thru to adjacent upstream and downstream chains of heaters. The junction block contains a ground lug to be connected to the chassis of the system, providing system grounding. Multiple power kits may be required based on the number of heater jackets in the chain requiring power.
