1- Does the JSC-88A require a ground or neutral connection to function?
YES, otherwise neither of the 3 LED lights will turn on.
2- Is it still possible to connect a JSC-88A to a fully floating electrical system (Delta) without a ground?
YES, if you use our KD-Kit wiring kit, it will create an artificial neutral from the 3 phases that supply the voltage detector. However, the presence of 2 or more phases is required so that this neutral can function properly and allow the JSC-88A LED lights to turn on. If there is only one phase, there is no return path, therefore, none of the 3 LED lights will turn on.
3- Will the 3 LED lights on the JSC-88A turn on if the KA-Kit wiring kit is connected to resistors placed on the JSC-88A end instead of the switch end?
NO, because the KA wiring kit has a direction and the resistors must always be installed in the switch side.
4- Can the JSC-88A be used to detect a phase loss?
NO, because its primary function is to detect the presence of voltage when a master switch is shut off. When a phase loss occurs, regeneration produced by the other two phases onto the missing phase will allow the 3 LED lights to remain lit.
This is because there is also potential for reverse flow from the control transformer, the motor winding or even the electronic devices connected to said switch. All these possibilities will allow the JSC-88A to detect voltage that could be dangerous for the electrician or maintenance engineer. The JSC-88A is a device that was designed to save lives in an industrial environment by visually indicating the presence of a three-phase voltage.
5- Can I install a JSC-88A on any electrical system?
NO, because the JSC-88A requires a ground or neutral connection to light up.
6- When installing the KA-Kit voltage reducer kits with a JSC-88A, can the wires be installed in any direction?
NO, because the KA wiring kit has to be installed in the right direction for the JSC-88A LED lights to turn on correctly. And, secondly, for security reasons mentioned in number 8.
