2. Introduction
2.1 General
The working conditions Act (ARBO-law) is intended to ensure the safety
of the employee in the workplace. In EN 50110 and NEN 3140, the
safety requirements and tests relating to the electrical installation and
electrical appliances/tools further developed.
2.1.1 Intended use
The RCT-C tester is intended to be used for checking of the safety of
electrical installations.
The RCT-S is intended for execution of all tests concerning different
protective switches with differential current protection. If the instru-
ment is used in manner not specified in this user manual, the protec-
tion provided by the instrument may be impaired and the supplier is
excluded from any responsibility.
Structure
The RCT-S is an electronic controlled instrument intended for the
execution of all tests concerning different protective switches with dif-
ferential current protection (with or without switch-off delay)
RCD types which can be tested by RCT-S:
1. The sensitivity according to the form of the fault current
- type AC
2. The disconnection delay
- without delay (standard type)
- with delay (selective type)
3. The rated values of the fault currents
-10 mA; 30 mA; 100 mA; 300 mA; 500 mA ; 650mA
Connection
The instrument is powered by four AA batteries. The tester is provided
with a on/off switch and can after powering up the instrument, be used
at once.
Measuring
The following measurements can be executed by the instrument:
1. The tripping time (t) at the current of IΔN
2. The trip out current (IΔ)
3. The mains voltage between the phase and the protective earth
terminals
