# Update allowed phases

`POST /loadpoints/{id}/phases/{phases}`

Updates the allowed phases of the loadpoint. Selects the desired phase mode for chargers with automatic phase switching. For manual phase switching chargers (via cable or Lasttrennschalter) this value tells evcc the actual phases.

## Path parameters

- `id` integer, required — Loadpoint index starting at 1.
- `phases` '0' | '1' | '3', required — Number of phases. (0: auto, 1: 1-phase, 3: 3-phase)

## Response `200`

Success - Number result

- number

## Other responses

- `400` — Invalid phases-value. You have most likely entered the value 0 for a wallbox that cannot switch phases automatically.
