The SAFEGATE stray current manager is designed to detect and stop stray current that results from unbalanced power systems.
The stray current seeks an electrical path through equipment and components to grounds that have less resistance than power company grounds. This means that equipment and components, such as rebar in pools, and steel tank walls that are in contact with ground potential water will become sacrificial anodes and be slowly destroyed without the stray current manager. This system costs significantly less than other corrosion protection systems.

Internally, the device appears to be one continuous electrical path through connected proprietary metal plates of differing materials. The composition of the proprietary metal and its position within the path are what enables the Safegate to exclude voltage below 1 volt.

Where each of the plates meets, there is a bond. Each material-to-material bond is "balanced, and this is where a voltage ascension barrier or threshold forms.

These bonds prevent AC and DC current below 1 volt from passing. Voltage above 1 volt passes through the Safegate with basically no resistance. In extreme cases where a surge or lighting strike occurs, and the operating Amperage/Voltage of the Safegate is exceeded, the internal proprietary metal plates will always "melt" together. This allows the device to still function as a continuous electrical connection by creating a "short" between the load and line side. It will no longer manage stray current at this point, but still completes the required bonding and grounding path.

It will never act as a fuse, or create an "open" circuit within the ground and bonding path.
