Electrical installation must be done by authorized person according to device
capacity and with suitable diameter cable which is determined according to
cable length. Electrical installation must have suitable specification for cut off
boiler power and residual current device that has ampere value and fuse
separately. Fuse must be near to device. Grounding of device must absolutely
be done. If there is not grounding at the place that device was installed,
grounding must be made for device authorized person. Grounding must be
controlled if it is operative or not by authorized personnel in determined period.
Fuse must be located near the device; there must be cable after fuse which is
enough as making connection to device. Connection of cables to device must
be made by authorized personnel. Water heater capacity and cable sections
which are calculated cable length, residual current device and fuse ampere
values can be seen at following table.
