A licensed electrician mounts it next to the breaker panel and connects it through 20-amp breakers. From there, EMP Shield says it defends the home's wiring against the E1, E2 and E3 phases of an EMP, coronal mass ejections (CME), lightning strikes and power surges.\u003c\/p\u003e\n\u003cp\u003eThis is the version for surface-mount panels, where the unit can sit on the wall beside the panel and connect through rigid conduit. Its 12 AWG copper leads come preconnected from EMP Shield, and its two green lights face you whenever you walk past the panel.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cbr\u003e\n\u003ch3\u003eEMP Shield Wired Home EMP Protection Features\u003c\/h3\u003e\n\u003ch4\u003ePreconnected Copper Leads Save Wiring Steps\u003c\/h4\u003e\n\u003cp\u003eEMP Shield says the W version comes with preconnected 12 AWG copper wire. The label marks the color code, L1 black, L2 red, neutral white and ground green. Your electrician threads the leads through the conduit into the panel and lands them on the selected breakers and the neutral.\u003c\/p\u003e\n\u003ch4\u003eFront-Facing Lights Confirm It Is Working\u003c\/h4\u003e\n\u003cp\u003eTwo green diagnostic lights, marked L1 and L2, sit on the face of the unit. EMP Shield says they come on once power is restored and show that the unit is in place and monitoring the incoming supply. EMP Shield also asks for a mounting spot with good visibility of these lights.\u003c\/p\u003e\n\u003ch4\u003eUp To 228,000 Amps Per Phase\u003c\/h4\u003e\n\u003cp\u003eEMP Shield lists the unit as capable of withstanding up to 228,000 amps per phase, with a nominal discharge current of 114kA.

Each phase has its own solid-state semiconductor circuitry and its own fuse, and EMP Shield lists IEEE C62.41-1991 category A and B combination wave suppression.\u003c\/p\u003e\n\u003ch4\u003eLab Testing And Listing Claims From EMP Shield\u003c\/h4\u003e\n\u003cp\u003eEMP Shield says it tested its design at Keystone Compliance against MIL-STD-188-125-1, MIL-STD-461G, MIL-STD-464C and RS-105, with RS-105 run at 50 kV\/m and 90 kV\/m. Keystone Compliance itself does not endorse any product. EMP Shield also says the Department of Homeland Security lists its products in an EMP resilience report, and it calls this model UL 1449 Type 2 compliant.\u003c\/p\u003e\n\u003ch4\u003eNEMA 4 Box With An Integrated Conduit Port\u003c\/h4\u003e\n\u003cp\u003eIts NEMA 4 plastic housing has a single conduit entrance port for the leads. EMP Shield says the J-box style housing simplifies mounting in typical frame construction.

The concealed SP-120-240-RL is secured inside the breaker box for flush panels and sends its lights to a small LED box on the exterior. If your panel is surface-mounted and you have wall space beside it, the W model is the simpler match.\u003c\/p\u003e\n\u003ch4\u003eWhole-Home Panel Unit Versus Plug-In Unit\u003c\/h4\u003e\n\u003cp\u003eA plug-in protector only helps the devices on the outlet it serves, and you need one in every room you care about. The wired unit is connected once at the breaker panel and watches the circuits that panel supplies, including appliances wired straight into the house.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003eBuyer Guidance\u003c\/h3\u003e\n\u003ch4\u003ePicking The Mounting Spot\u003c\/h4\u003e\n\u003cp\u003eEMP Shield says to mount the unit as close as possible to the panel, keep connection leads short and allow at least one inch of clearance from the edge of the panel cover. On a surface-mount panel the unit may connect with rigid conduit to any conduit port. Leads should not be coiled or looped.\u003c\/p\u003e\n\u003ch4\u003eWho Should Install It\u003c\/h4\u003e\n\u003cp\u003eEMP Shield calls for a licensed electrician and an install that follows local electrical codes. The unit needs a disconnect such as 20-amp breakers or a 20-amp fused disconnect switch, and it works only with copper or copper-clad wire. EMP Shield estimates 10 to 15 minutes of electrician time.\u003c\/p\u003e\n\u003ch4\u003eThis May Be A Good Fit If\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eYour home runs on 120\/240V split-phase power\u003c\/li\u003e\n\u003cli\u003eYour breaker panel is \u003cspan style=\"white-space: nowrap;\"\u003esurface-mounted\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003eYou want the status lights on the unit itself\u003c\/li\u003e\n\u003cli\u003eYou prefer leads that come already attached\u003c\/li\u003e\n\u003cli\u003eYou will hire a licensed electrician\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003ch3\u003eCommon Questions\u003c\/h3\u003e\n\u003ch4\u003eWhich Breakers Does It Connect To?\u003c\/h4\u003e\n\u003cp\u003eEMP Shield recommends 20-amp breakers placed as close as possible to each service entrance lug, and says they may be shared with branch circuit leads. The breakers add failure protection and give a disconnect for servicing. EMP Shield warns never to connect the leads directly to the service entrance lugs.\u003c\/p\u003e\n\u003ch4\u003eWhat If One Of The Lights Turns Off?\u003c\/h4\u003e\n\u003cp\u003eHave an electrician confirm whether that phase has power.

A unit destroyed by lightning can be replaced for $50 by sending the damaged unit to EMP Shield. EMP Shield's separate protection policy may pay up to $25,000 for damaged connected electronics if its conditions are met, such as installation by a licensed electrician and a claim filed within 30 days.\u003c\/p\u003e\n\u003cbr\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x EMP Shield SP-120-240-W Wired Home Unit With Preconnected Leads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e\n\u003ch3\u003eProtection You Can Check At A Glance\u003c\/h3\u003e\n\u003cp\u003eThe EMP Shield Wired Home EMP Protection unit gives a surface-mount 120\/240V panel EMP, CME, lightning and surge protection with its lights in plain sight.
