Where to Buy TPI Products

The TPI 85 Multi- Function Earth Loop Tester is a state of the art, easy to use instrument that is designed to test the safety of an electrical appliance/installation. It can be used prior to or following any adjustment, replacement of components, or fault finding operations.

The instrument can be used to indicate in the order shown:

  • the correct or incorrect wiring of an electrical circuit
  • indicate the correct or incorrect voltage of the circuit
  • indicate the Earth – Loop Impedance of the circuit
  • indicate correct or incorrect polarity

The instrument is ruggedly constructed and comes with a 3 Year Limited Guarantee.

The TPI 85 Multi-Function Earth Loop Tester Kit comes complete
with:

  • One Test lead incorporating a UK style 3 pin plug (fitted with a 13 Amp fuse) at one end and a IEC type connector fitted at the other end, which interfaces with the instrument for testing via Socket Outlets
  • A second test lead which is equipped with 3 separate probes to enable testing via connections other than where a Socket Outlet is present
  • Instruction Manual
  • Carry Case

Building Regulations – Part P (Electrical Safety)

The use of the TPI 85 tester ensures compliance with Part P of the Building Regulations while carrying out maintenance or fault finding activities on all appliance or installations connected to an electricity supply. The 2 test lead sets (included) enable the testing of: Socket Outlets At the point of connection of any in-line electrical item, such as pump, fan or motorised valve.

The TPI 85C3 kit comes complete with TPI 85 unit, three-pin plug connector, fly test lead set with connectors all in a specially designed zippered carry case. Easy to Use Mains powered (no batteries required)

  • Indicates Earth-Loop Impedance of the circuit
  • Identifies correct or incorrect wiring of an electrical circuit
  • Shows correct or incorrect voltage
  • Identifies polarity faults CE Marked Wiring Test Detects missing E or N
  • Detects L-E or L-N swap Polarity Test
  • Detects Live-Earth phase reversal by use of touchpad Fault indicated by chart on front of instrument

Important: This instrument is designed to operate safely on domestic low voltage alternating current (AC) systems only, which normally operate at around 230V AC. It should not normally be subjected to voltages above 300V AC nor used on Direct Current (DC) circuits.
