L-L, L-G= 1meg ohms or higher. That's it. In the event you do not possess a capacitance meter, use an inexpensive analog VOM and during the resistance check look for needle swing towards zero but finally returning to infinite. If it does the needle swing and settling back on infinite, you are good to go. Note: MFD readings need not be exact but +/- 1MFD should suffice. Your hands must NOT be touching the leads whilst testing and the device MUST be completely disconnected-all 3 leads. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Delta's surge arrestors and surge capacitors are awesome. They give a great deal of peace of ... *by M***D on Reviewed in the United States on September 4, 2014* Delta's surge arrestors and surge capacitors are awesome. They give a great deal of peace of mind during lightning storms and line work - you won't realize how much they're doing for you until years later when you think - 'Hey, none of my stuff has been fried in a long time! I wonder if it's the CA302/LA302?' My guess is that it probably has something to do with it. I've got these things in my house on the grid side, inverter side of a Solar array and the DC side of the solar array. The pro solar installers swear by em, and I've put them in friends and family's houses. Great tech. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Surge Capacitor *by J***M on Reviewed in the United States on August 15, 2013* Bought this capacitor in conjunction with a solar panel instal. Purpose to protect sensitive inverter against problems on the AC line. Was a bit hard to find even from solar stores. This was a good price for this object and it is easy to install. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Good lengths of wire, to fit inside a 200 amp panel. *by R***C on Reviewed in the United States on December 5, 2021* The wiring was long enough so that the unit could sit at the bottom of a 200 amp electric panel and tie in at the top, nearest to the line input. No idea whether it will work, hopefully I will never find out. Installed toether with a lightning arrestor, which has similar characteristics. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/20566696-delta-ca302-r-2-pole-125-250vac-single-phase-surge](https://www.desertcart.tw/products/20566696-delta-ca302-r-2-pole-125-250vac-single-phase-surge) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-22*
