thanks for the response...the price i got 1 of these for was just under 20 and with tax was about 20 even. No shipping. The contactor you had given was 9 bucks and 16 in shipping. I am planning on using 1 5500w element and one 4500w element. I have most of the exterior parts and am now moving to the interior. I was sure these were going to work but the relay...contactor thing makes me a little uneasy. After hours online searching and finding most to be in that 30-40 range i was more than happy to get them for 20. As long as they work for said application. I still need to buy 2 more and now will rest easier. Thank you very very much.
