We were using Sure Power isolators for a relatively high demand electrical system. With just 8 prototypes in the field, we had 100% failure rate and less than desirable service from the manufacturer. I found POWER-GATE on-line in a Google search. It looked to be able to provide everything we needed. I called in and discussed the application. Service was prompt and professional. It is a considerably more expensive product than the Sure Power but we have been up and running for several months with no issues. Installation was easy and I would definitely recommend.
