How can the T.R.A.P.™ be effective against an EMP when it’s so small?
The danger to vehicles from an EMP is the high voltage that is introduced on the cables from E1 and E2. Those transient voltages are extremely brief in time (from nanoseconds to microseconds) and can therefore be suppressed using small devices. This is distinctly different than the case with homes, which would also experience a powerful E1 current surge from the power grid.

Is it ok to use multiple T.R.A.P.s in one vehicle?

Yes, putting energy “traps” at multiple points in your vehicle does a better job of shunting away the unwanted energy. Maximum protection is achieved by using a T.R.A.P.™ in every auxiliary power outlet, as well as using the T.R.A.P.™-B across the vehicle’s battery.

Does a T.R.A.P.™ protect a vehicle even when the vehicle is powered off?
The T.R.A.P.™ provides transient protection even with the ignition switch turned off because interconnected cable assemblies can still receive damaging energy. The T.R.A.P.™ continues to act as a high-frequency energy sink even when the vehicle is unpowered.

Will a T.R.A.P.™ or T.R.A.P.™-B drain my battery?
T.R.A.P.™ products draw essentially zero current except when there is a significant overvoltage, so they won’t drain your battery.

How do I change out the ring terminals on the T.R.A.P.-B?
Below is a video showing the steps to swap the ring terminals on the T.R.A.P.-B. Please see the dropdown menu above for a larger ring terminal set.
