TRISAN S8 Appliance Categories and test sequences.
16 3-Pin Run Test CLASS II
For appliances that have an earth pin that serves as a grounding for EMC currents. This is considered a
functional earth not a protective earth.
There is no exposed conductive chassis earth.
Given that it is connected to the supply earth it does have a protective purpose. If the supply cord is cut
or damaged during operation of the appliance an RCD would be tripped before a circuit breaker trip.
These appliances are permitted to have leakage currents up to 5mA.
An earth return cloak or probe is used to touch the surface of the appliance and cord especially in worn
areas, This provides an additional return path to earth for surface leakage currents.
The S8 prompts a warning for leakage currents above 1mA. But fails leakage current above 5mA.
The tests conducted are as follows:
1. Electrical continuity A-N < 100k….. PASS
2. Leakage current < 5mA. …………...PASS
3. Duration of test 30 seconds……. touch and release RESET button to terminate test sooner.
17 Long Run Test CLASS I
This test offers a test duration of 10 minutes.
Identical to run test in specifications, but allows appliances to fully energise over time.
(i.e.) computers and motorised appliances with timed contactors.
18 3 Phase Leakage Run test (option) CLASS I
Requires 3 phase test lead set 10,20,32 and 50 amp. Available in 4 or 5 pin
Tester powered by mains or battery.
The test measures: Electrical continuity ………load < 100k ohms. Ensures load is powered
Earth resistance…………….threshold <1 ohm. Is a PASS
Leakage current……...Threshold < 5mA. Is a PASS
Duration of test is up to 45 minutes. Touch and release RESET button to terminate test sooner.
