Battery boxes can be tested for faults by placing the box on a metal plate. By applying a test voltage to an electrode inside the box, the moulding can be checked thoroughly - particularly at the injection points - and any faults found. Defects will be identified by a spark passing from the electrode, through the defect itself, to earth (the conductive material placed outside the battery box.

Martindale Electric Co. Ltd
The most popular socket tester available - detects 28 fault conditions.
A quick and easy way to ensure that 13A sockets are correctly wired, indicated by 3 bright long life LEDs.
Wiring faults are indicated by one or more of the LEDs failing to illuminate, with the pattern of lit LEDs indicating the type of fault detected. This fail-safe system means that any LED not lit indicates a fault. The robust ABS housing has a sculpted shape for easy removal and there is a look up chart on the tester for quick fault diagnosis.
The plug induces less than 5mA of earth leakage, well below RCD trip thresholds.

Standard Electric Works Co., Ltd
● Microprocessor-controlled.● Measures Earth Resistance without the need for poles in the ground or external measuring wires.● Earth measurement uses the real earth current path and the current generated by the electric network, without the need for any disconnection.● The Earth Resistance displayed is exactly the earth resistance that the earth current will need to go through if an earth fault occurs. (you do not need to add all the bonding points and connection paths)● Displays voltage supply at the transformer(Line to Neutral), without loading the transformer.● Single one smart push button operation; ON, Scroll through results and menus.● Checks wiring integrity (LEDs).● Auto-off / Auto-ranging (software range).● Color-coded test leads.● Combined prospective short circuit current, loop, and earth tester.● Loop test for L-E and PSC between L-N.● Voltage test L-N.● Display can be customized for large orders.

CZ20054 -
Aegis Pty. Ltd.
Australian and New Zealand standards mandate testing of fault loop impedance on circuits not protected by RCD's, both at installation and after maintenance. The CZ20054 Loop Impedance Tester conducts earth fault loop impedance and prospective short circuit current (PSC) tests. The Aegis Loop Impedance Tester takes the confusion out of loop/psc testing by providing an automatic wiring check upon connection and single button operation.

Shenzhen Chuangxin Instruments Co., Ltd.
Ground Earth Resistance Tester verifies the integrity (continuity) of the protective bonding of the equipment (Class I equipment) designed to secure safety through the basic insulation and protective earthing. It is also called earth (ground) bonding test. If the continuity of the protective bonding is confirmed, we can conclude that the equipment has the requirements for preventing electric shock even if the insulation between the primary circuit and the accessible conductive section fails and a fault current flows through the distribution system.

Bender Inc.
Ground-fault products are used to monitor grounded systems (ungrounded and grounded) for fault currents or residual currents. The sum of all conductors except the protective earth conductor is measured by means of measuring current transformers.In general, ground-fault monitors (RCM - residual current monitors) are used to send a message to the user even before reaching the shutdown threshold of the GFCI. Ground-fault monitors detect deteriorations of the insulation level at an early stage and in a reliable way.
