What cable size should I use

⚠️ Important: The following information is for guidance only.
PlugStream products must be installed by trained professionals who are already familiar with these requirements.

Overview

PlugStream can supply up to 32A to an EV. This is a high load on a low-voltage supply, so selecting the correct cable is essential to prevent overheating, minimise voltage drop, and ensure reliable operation.

  • The minimum cable size for a 32A feed is 6.0 mm².
  • The actual cable size required depends on the installation method and the length of the run. For longer distances, oversizing the cable may be necessary to reduce voltage drop and power losses.
  • PlugStream’s main terminals accept conductors up to 16 mm².

Cable preparation

  1. Route the mains cable through the fitted cable gland.
  2. Strip the outer sheath, leaving a small amount of slack so all cores reach the terminal blocks.
  3. Strip approximately 18 mm of insulation from each conductor.
  4. If using hard-wired CT clamps, install them at this stage. We recommend either:
  5. A specialist cable gland that can accommodate multiple cables while maintaining IP integrity, or
  6. Two separate glands to ensure a proper seal.

To connect, insert a correctly sized screwdriver into the slot of the spring terminal to open it, push the conductor fully home, then remove the screwdriver. Always check the conductor is securely clamped.

Cable and Gland Requirements

  • Conductor size: Typically 4 mm² to 10 mm², depending on the installation.
  • Gland size: Minimum 16 mm, maximum 25 mm.
  • Gland types:
  • Standard stuffing glands (for non-armoured cable).
  • SWA CW outdoor glands (for armoured cable).

⚠️ The choice of cable and gland is the installer’s responsibility and must be determined based on the specifics of each installation. Using an unsuitable gland may compromise sealing and invalidate the warranty if identified as a point of failure.
