Customer Questions & Answers

wiring the surge protector to the main lugs instead of wiring to a breaker

i pulled the meter to kill the power and mounted the surge protector to the side of breaker panel and connected the leads to the main lugs of the breaker panel. Is this way of installation wrong.
Asked by: Jim78133
It is NOT correct! The components inside the device can fail (short circuit) and without a breaker to limit the current the device or wiring could go up in flames. Even if you connect to the load side of the main breaker, the let-through current based on the trip rating of the main breaker is so high you're still likely to burn-up the unit.

Can this be used as single pole for 30 amp RV ( one black and white wire connected, cap extra black)

Asked by: LEH
Yes. If the RV service is 120V, you'd only be using half the device. The protection ratings are for line-to-line and line-to-neutral. Connecting as you suggest would provide the line-to-neutral protection. (The interior components are passive and have no way of 'knowing' the other -black- leg isn't connected.)

On a mobile home is it better mounting surge protector in main panel outside or house panel. Main panel has room for bre

Asked by: dave
It is suggested that surge protective device be mounted as close to the incoming main as possible to provide protection for downstream devices. Connecting the SDSA1175 leads to a 2-pole 15-30 ampere branch circuit breaker is recommended means of connection.

Rated 3 out of 5 by from Beware TYPE 1 Please note that "TYPE 1" in the description means that this model is to be used if you have lightning rods. Otherwise "TYPE 2" should be used. Most surge protectors sold here are really type 2. Nowhere on the box did it mention which type it is. I found out I have the wrong type after I bought it in the store and installed it then saw the description on line. The unit itself seems OK and the install was easy.

Rated 5 out of 5 by from Good whole house surge protector Installed this whole house surge protector to help to protect all electrical devices in a home from electrical surges after having some hard wired electronic devices get destroyed in the past by electrical surges. Electrical surges can originate external to a home from electrical disturbances generated during bad weather or from a utility company or internal to a home from large appliances operating. This whole house surge protector makes it possible to provide surge protection for all electrical devices and electronics in a home through using one protection device including for devices that are hard wired that can't easily be plugged into in-line surge protectors such as lights and major appliances, etc.. Noticed an immediate difference with this surge protector installed with the improved operation of a digital to analog cable TV converter that no longer resets each time a furnace operates. Before installing this surge protector a digital to analog cable TV converter reset each time a furnace operated even with the power supply for the digital to analog cable TV converter plugged into a quality multiple MOV surge protection device designed to protect computers. This surge protector is a good investment to help protect electrical devices and electronics throughout a home including LED light bulbs, occupancy detectors, computers, televisions, appliances, etc. from being damaged or destroyed by electrical surges. Was able to install this surge protector above a bottom main power entry cable in a 16 circuit breaker box used in Mobile homes by using a 1" to 1/2" reducing washer and a 1" knock-out hole in the top of the circuit breaker box that is intended for a top main power entry cable. This whole house surge protector is an ideal compact physical size and the only model that would fit dimensionally in my application. The single green LED on this surge protector provides a simple indication that this surge protector is operational and does not require replacement.

Rated 5 out of 5 by from Great Device I installed this at my new high efficiency furnace and it was super easy to install. I also installed their HEPD 80 at my main panel to cover the rest of my house. Works great and now i don't have to worry about losing my 10K furnace in the middle of winter.
