hen you have traced the fault to a single

appliance or circuit, it must then be checked for

earth leakage by a competent person.

Imprinted Leakage

Imprinted Leakage typically occurs when equipment

using a Switched Mode Power Supply Unit, (SMPSU),

is connected to your system.

Pay close attention to earthing of equipment. Equipment is often installed

without adequate earth bonding. Please consult the equipment's

installation manual, or contact the manufacturers for more information.

Earth bonding point

Because of the way SMPSU's operate, some of them leak power into the boat's

earth wiring. This can cause the galvanic isolators light to come on, as the isolator

correctly detects the leakage.

Imprinted Leakage is traced in exactly the same way as for Mains Leakage.

However, when you track the problem down to an individual appliance, it may still

pass an Earth Leakage test. In that case, it's likely that the problem is Imprinted

Leakage. Imprinted Leakage is often due to incorrect installation, but can also result

from design or manufacturing issues.

Equipment utilising SMPSU's include, Battery

Chargers, Computers, TV's, Domestic Appliances,

Phone Chargers etc.

In our experience, battery chargers are often the cause

of imprinted leakage. CE regulations require that

equipment should not create this kind of interference,

but not all equipment is as "clean" as it should be.
