Short answer: An MFT crocodile clip for an earth bar must be selected from the multifunction tester manufacturer's approved accessories and used within the specified installation-test procedure. The Leadbrand listing only documents a GS1023 probe-and-clip kit, a 4 mm banana format and basic materials. It does not state MFT compatibility, voltage, current, measurement category, fuse protection or jaw insulation. Those omissions are decisive for installation work: do not use this listing as an earth-bar test lead unless the instrument manufacturer and the accessory markings explicitly support the exact test.

Treat MFT compatibility as a documented requirement

Installation testers can use proprietary lead arrangements, remote probes or protected connectors even when a nominal 4 mm format appears familiar. Check the exact MFT manual and accessory reference.

The live Leadbrand page does not name any MFT or earth-bar procedure. Its broad product category cannot replace instrument-specific approval.

Plan the test before connecting

Determine whether the applicable test is performed dead or live and follow the tester and installation procedure exactly. Earth-bar access can expose adjacent conductive parts, so uncontrolled clip geometry is a serious mismatch.

HSE GS38 addresses suitable test leads, protected probes and limiting exposed conductive metal. Where this product does not document those controls, select an accessory that does.

  1. Identify the exact MFT model and intended test.
  2. Read the instrument manufacturer's connection diagram.
  3. Confirm the circuit state and safe-isolation requirements.
  4. Verify connector, jaw, insulation and rating details.
  5. Use only the approved accessory and stop if any marking is missing.

Avoid using a clip as a universal earth connection

A clip that grips an earth bar physically may still be unsuitable electrically or mechanically. It could expose too much metal, contact an adjacent part or detach when the lead moves.

Do not improvise extensions, adapters or stacked connectors. Each added component needs to be documented for the instrument, circuit and environment.

Limits that rule out an assumption

The manufacturer does not specify MFT models, earth-bar use, voltage, current, measurement category, fuse protection, connector shrouding, jaw dimensions or conformity standards on the current page.

Until those facts are supplied, treat the GS1023 kit as an unverified general accessory set, not an installation-testing lead system.

For an earth bar, choose the exact protected clip and lead named by the MFT manufacturer rather than relying on a generic 4 mm description. Read Multimeter Lead Kit with Clips and Hooks: What to Check for related guidance. Read 4 mm Banana Plug Test Leads for a Multimeter: UK Checks for related guidance. Review the documented specification on the Multimeter test lead kit product page before ordering.
