GENERAL PRESENTATION

These decade boxes come in metal casing with a male terminal
linked to the casing for earthing and female terminals for a
direct connection to each decade.

Recommendations for use:

Use short and strong section cables for low values.
Do not exceed the maximum intensity allowed for each decade.
The access terminals for each decade are used to produce
resistant dividers.
