Mounting and installation information for junction boxes
Junction boxes are used to connect cables and can be
mounted in all kinds of areas. With regard to the ambient
conditions, several factors and standardised specifica-
tions must be taken into account, in order to select the
right junction box for the intended place of use. Thus,
with installations in outdoor areas or in damp or wet envir-
onments, it is necessary to estimate exactly how strong
the load from weathering or possibly damaging envir-
onmental influences is and which protective measures
are necessary. The division into different protection rat-
ings, also termed IP codes, provides information on how
strongly a junction box is protected against contact and
the harmful ingress of water. By contrast, the so-called IK
code represents the protection rating against mechanic-
al loads. DIN VDE 0100 is an erection requirement and
specifies which requirements a junction box must fulfil in
specific installation areas. To guarantee a safe device in-
stallation, all these factors must be checked in individual
cases and observed during the selection.
