# How many amps can a NODE chain have?

How many NODEs and consumers can be connected in a chain depends on the cable cross-section. The power cable must be able to carry at least 20 A continuously to match the maximum load capacity of the NODE chain. We recommend a cross-section of 4 mm² for this.

The NODE itself limits the chain: a maximum of 20 A can be switched through a NODE. Since all the current in a chain flows through the first NODE, the sum of all connected consumers must not exceed this value. The fuse and cable design must therefore always be rated for a maximum of 20 A.
