## Questions & Answers

**Q: Not for 240??? I don't see 2 black wires and ground or neutral...**
A: Thats correct. This is for a 120 VAC L1 only.  You would need to buy the 240 VAC dual line (L1/L2) sussurge protector for a few buck more.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good
*by A***. on September 7, 2025*

Excellent product, easy to install

### ⭐⭐⭐⭐⭐ Easy install
*by H***E on August 31, 2024*

Easy install, great add on for excess power surges

### ⭐⭐⭐⭐⭐ Installed on panel, no more nuisance alarms
*by B***H on October 26, 2020*

We used to get nuisance fire alarms with a certain frequency, always at ~2:30am, likely due to utility grid switching (voltage surges). That gets pretty old when you have little kids. I installed this surge protector on the smoke detector circuit on the panel and - so far - no further nuisance alarms. Directions were easy (if you know your way around a panel). Appears to work well.
