  • What kind of protector should I use if I don t have a terminal box

    What kind of protector should I use if I don t have a terminal box

    You can start with installing a “circuit panel” or “service entrance” style surge protector (also referred to as a surge suppression device) in your home. This device either reduces electricity spikes, or stops them from entering the house all together. Surge protectors typically contain components like Metal Oxide Varistors (MOVs) that absorb and mitigate these. Plug-on neutral SPDs are especially useful in systems with limited space because they do not require extra terminals or wiring. Your home will remain safe even without a junction box if all electrical connections are secured. That. I have a PC that I would like to protect and my plan is to get a zero surge unit which to my understanding does not require a ground wire to provide protection against 2 of 3 types of surges.
