My wife understands the 125 second "delay" after the power cord is plugged in and lets me know when she is ready to run out the slide outs. I'm outside doing the other hookups while she cares for the interior. We setup and tear down almost every night because of our travels for work [Many camp grounds a week]. And yes they are out there even in a different space from last time in a camp that was "good" last time. Would absolutely replace with the same item. ### ⭐⭐⭐ TRC 34560 Substandard *by J***E on Reviewed in the United States on August 24, 2014* I guess this works OK. I say that because as I was wiring it into my RV, the lights continually showed a fault. I called my electrician who came over (and charged me for his visit). He checked the wiring which was right, checked the voltage and it was right-on, the electrician called tech support and finally got someone. They went through some tests and determined that, while the unit was working as it should, there was something wrong with the circuit board and the unit needed to be replaced, which they will do under warranty. So, I rated the unit lower due not testing the unit while at the factory. ### ⭐⭐⭐⭐⭐ Easy to install and piece of mind protection *by G***G on Reviewed in the United States on May 19, 2015* Easy to install with a small drill, screwdriver and wire crimper. I used the following additional parts for installation.1. Gardner Bender 10-106 Terminal Ring, 12-10 AWG, Stud Sz 8-10, Yellow2. 10/3 AWG Triplex Tinned Marine Wire, Black/Green/WhiteThe 2-3 minute delay is great for protecting the AC compressor when the power cuts out. Some people have complained about a humming noise. Its true, this device emits an sound, but that is not uncommon for electrical devices. Install this in a cabinet and you will not hear the sound. My AC compressor makes more noise than this device, so I never hear it and it is installed in the galley cabinet of my teardrop. --- ## 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.sg/products/17775816-technology-research-34520-002-120-volt-30-amp-hardwire-surge](https://www.desertcart.sg/products/17775816-technology-research-34520-002-120-volt-30-amp-hardwire-surge) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-10-12*
