Q: Can I install the units myself?

Q: Does anyone else make a similar product?
A: No. Our surge protection technology is patented. Other competing products use different technology, with "spark-gaps", which will wear out over time. Our patented Lightning Arrestors, Surge Capacitors and Data Line Protectors come with a Lifetime Guarantee against an unlimited number of surges.

Q: Can I purchase Delta Surge Protectors in stores?
A: No. We are exclusive dealers of Delta Lightning Arrestor and Delta Surge Capacitor units, which are sold only over the internet, shipped direct from our manufacturing warehouse. We have seen other online retailers offering our products on occasion, but we caution against buying "used" units or units that come from "questionable" sources. We stand behind our Delta brand products.

Q: Will your units protect me against any surge that nature can dish out?
A: Unfortunately, no one can completely safeguard you against the vagaries of Mother Nature, but our packages provide around a 95% effective rate of protection - considered to be the best in the business.

Q: Where are your products made?
A: All of our products are proudly made in the great state of Texas, U.S.A. and have been for over 40 years.

Q: I don't know much about what Delta Lightning Arrestors and Delta Surge Capacitors and Surge Protectors can do for me, but I know I need Whole House Surge Protection. Where do I start?
A: See our "Product Wizard".

Q: Does it matter if my home uses 110 Volts or 220 Volts?
A: No. The product wizard will guide you through this. If your building is wired for much higher voltages, such as for use with industrial equipment, such as oil and gas pumps, windmills, you will need a different type of Delta Surge Protector and Delta Lightning Arrestor. The product wizard will make sure that you have the appropriate package.

Q: How reliable are Delta units?
A: While there is no lightning arrestor product, surge protector or surge capacitor on the market today that can guarantee 100% protection against the unpredictable wrath of Mother Nature's storm clouds, our Lightning Arrestors, Surge Capacitors and Data Line Protectors (especially when a Delta Residential Package or Delta Commercial Package is correctly installed) allow one install in the circuit breaker box to provide whole home surge protection to greatly reduce the probability of electrical damage and increase the rate of protection to nearly 100%, even in extremely harsh, unfavorable conditions.
