Almost everything in your home (except your couch and other furniture pieces) relies on electricity. If anything goes wrong in the electrical system, the entire house will be affected and at risk. This single fact means that you are not immune to a power surge if it occurs.

The whole house surge protector protects all your electronic devices and electrical appliances from power surges. Luckily a whole house surge protector can help protect every single outlet in your home against both internal and external power surges.

What does a whole house surge protector do?

A whole-house surge protector acts as a voltage breaker. It will continuously regulate the voltage that flows through your wiring. Connected to the circuits in the electrical panel, a whole-house surge protector works by redirecting the surge.

They do so by blocking or grounding the high voltage flow and limiting the current that flows through your house. Think of it as a pressure relief valve. This is different from other types of protectors that may attempt to absorb the surge.

Is it affordable?

The best defense against electrical spikes is the installation of a whole house surge protector in your home. A whole house surge protection device is an affordable option that is capable of protecting your electrical devices from up to 80% of power surges. The average cost is $100 to $250. You can expect a whole house surge protector to last between 2 and 5 years.

Steps to install the Eaton Whole House Surge Protector:

Eaton Whole House Surge Protector Installation Decide on a Location
Decide on a location for your Eaton whole house surge protector

Step 1

While installing an Eaton whole house surge protector, you should place the Eaton PH and PV device close to the load you want to get protected so that it can get optimal protection. Try keeping the wiring of the device as short and straight as possible from the Eaton output terminals to the electronic equipment’s input terminals. In such a way, the device would not act as an antenna and avoid picking up high-frequency noise from the environment. It is not obligatory for the wiring length to the input terminals of the Eaton PH and PV to be short as it is not critical.

Step 2

Have you ever felt the pain of an electrical shock? Spoiler Alert: That crap hurts. So, in an effort to avoid that at all costs, lets practice SAFETY FIRST.
Before installing an Eaton whole house surge protector:
A.) You should Turn Off and Lock Out all power sources to the electric circuit before installing an Eaton whole house surge protector so that there would not be a risk of getting an electrical shock
B.) Use a portable voltmeter or other measuring devices to verify the disconnection of the power

Eaton Whole House Surge Protector DIN Rail Connection Step
Mount the Eaton Surge Protector on the DIN rail

Step 3

DIN rails are designed for securely attaching electrical products. In every Eaton chspt2ultra device, there would be a DIN Rail and two mounting screws to enclosure mounting. Do these two steps engage the DIN rail:
A.) By using the DIN Rail as a template, you’ll do the drilling of appropriate hole sizes. The hole size would depend on the material and thickness of the screws. 
B.) When you secure the DIN rail, you have to engage the Eaton Whole House Surge Protector base of the DIN Clip onto the DIN Rail.
C.) You would have to compress the DIN clip spring until engaging in the DIN Rails with the opposite side of the DIN Clip hook. For this, you would be a need to push the enclosure towards the Input terminal side of the enclosure bottom.
D.) After compressing the DIN clip spring, it’s time to release the DIN clip’s spring pressure. All this process would secure the surge protector enclosure to the DIN Rail.

Step 4

It would be helpful to follow the wiring diagram that comes with your device. I’ll also provide you some helpful tips to simplify the wiring process. You have to go on the input side of the Eaton device to install an overcurrent protection device. The following are some wiring instruction for Eaton PH device:
A.) From the overcurrent protection device, you have to take the wire to the input terminal of the Eaton chspt2ultra surge protector. The terminals on the device have marked as L, N, and G.
B.) To match the amperage of the Eaton overcurrent protection device you have to select wire gauge
C.) Select and ensure that you got the wires of the proper color. The ground can be green or yellow. The neutral should be of white or light blue, and the phase should be black or red. It would make it easy to detect the wiring onwards if there would be any need.
D.) After selecting the wires, now tighten all input and output terminal connections to 9 lb-in.
E.) You have to take the wire from the Eaton PH output terminals to the input terminals of the load you want to get protected.

F.) Now again, you need to tight all input and output terminal connections to 9 lb-in.

Step 5

Ok. Time to finish up the last few steps to get Eaton whole house surge protector operational.
A.) Go ahead and install the terminal block covers by pressing them into place on both the input and output terminals.
B.) There would be one N .O and one N .C contact in case the Form C contact gets used for remote monitoring. You can see the labeling of the terminal connections on the top of the enclosure.
C.) If you want to activate the system, you have to connect the Form C output terminals to an alarm, building monitoring system, or light.
D.) Now you should tight all Form C terminal connections to 4 lb-in to avoid any risk onwards.
E.) You should recheck all the connections to ensure there is nothing to worry about it.
F.) Now, as the installation got done so, you can restore power to the electrical circuit.
G.) You can check the status of the system through a green LED indicator as it would get illuminated.
