Q & A

Customer Q&A

Crutchfield asked  
Why did you buy this?

I am using this to protect a new microwave oven in a place where space is tight. It has a higher joule rating for protection than competitors, and specifies that it is certified under UL standard 1447. [ BYRON  Aug 17, 2018 ]
Need additional outlet protection for a motorized screen. [ Rafael  Mar 03, 2018 ]
Already am using a Panamax conditioner for my other equipment want to give my ceiling mounted projector a measure of surge protection. [ Rafael  Feb 13, 2018 ]
To protect ceiling mounted projector in media room [ Lorenzo  Jan 31, 2018 ]
A few weeks ago I had an extended call with Artie who made me aware that such a product exists. It will allow us to keep our wall mounted TV protected without having to deal with a power strip so the installation will be cleaner. [ Allison  Jul 21, 2017 ]
The Joule rating and clamping voltage were excellent compared to other brands. [ Domenick  Apr 07, 2017 ]
Looks better than equivalent Leviton duplex surge outlet [ ROBERT W  Dec 07, 2016 ]
Same reason, warranty protection. [ Terry  Nov 27, 2016 ]
Replacing TV's outlets with surge protection. [ kevin  Sep 22, 2016 ]
Number 1 it is a Panamax product and number 2, I like its combination surge and disconnect functions. I also like its over/under voltage protection. Most people do not know that surge protectors do not protect your equipment from short and long term voltage issues. [ Stephen D.  Sep 18, 2016 ]
For wall mounted TV surge protection. [ Alex  Sep 15, 2016 ]
Figured since I need to move the outlet anyway, why not up the protection level while I'm at it. [ Christopher  Apr 15, 2016 ]
protect new dishwasher [ Grady  Mar 30, 2016 ]
I use for about 6 years Panamax surge protector equipment after an extensive search on the web about recommended surge equipment. Panamax is the best equipment on the market and best value as well. [ PETER  Mar 28, 2016 ]
low profile [ JOHN  Feb 28, 2016 ]
surge protection without having surge strip [ PATRICK  Jan 17, 2016 ]
Good amount of surge protection for the money. Good option for behind flat panel tvs. [ MATTHEW  Jan 04, 2016 ]
surge protection for projector [ Brad  Dec 05, 2015 ]

I believe you can use this outside as long as there is no direct water contact Plus he's a protective cover [ Parker  Aug 22, 2017 ]
Hi Michael, I'm unaware of any temperature limits such as extremely hot or cold climates. My only advice on outdoor use would be to enclose the surge protector in an outdoor junction box for protection from the elements. Examples of enclosures would be 1) Taymac MM510C Weatherproof Single Outlet Cover Outdoor Receptacle Protector, used when the appliance is plugged in; and 2) Hubble-Bell MX1050S outlet cover which is closed when the appliance is not in use and unplugged. Also make sure the ground wire functions correctly. Polarity and ground testers are inexpensive and found at hardware stores. Hope this helps. Tom [ Thomas E.  Aug 21, 2017 ]
In no way, shape, or form should this be used outdoors or around any water whatsoever. This is a surge protector, NOT a ground fault device. [ Jim  Aug 21, 2017 ]
No I would not use this outdoors. I'd get a ground fault interruptor outlet made for outdoor use. [ Grant  Aug 21, 2017 ]
Outdoor sockets need to be GFCI. This is not a GFCI receptacle. If you wish to use it outdoors, you will need to also change the breaker on that circuit to a GFCI breaker. [ Adam  Aug 21, 2017 ]
Good question. My guess is that would depend on the size of the surge. [ Michael  May 29, 2017 ]
