Insulation resistance test M-Ohms

Bus to Braid Megohm Test (Attach + lead across both bus wires, attach – lead to braid/pigtail.) Note: Insulation resistance values for test for any particular circuit, should not vary more than 25% as a function of measuring voltage. Greater variances may indicate a problem with heat-tracing system.

• Set Megohm to perform 500 VDC test and test the cable. Turn on voltage after 1 minute, select Pass or Fail and record reading. NOTE: RAPID MAXIMUM DEFLECTION INDICATES A SHORT.

  Yes

  No

  N/A

• Enter reading.

• Set Megohm to perform 1000 VDC test and test the cable. . Turn on voltage after 1 minute, select Pass or Fail and record reading. NOTE: RAPID MAXIMUM DEFLECTION INDICATES A SHORT.

  Yes

  No

  N/A

• Enter reading.

• Set Megohm to perform 2500 VDC test and test the cable. . Turn on voltage after 1 minute, select Pass or Fail and record reading. NOTE: RAPID MAXIMUM DEFLECTION INDICATES A SHORT.

  Yes

  No

  N/A

• Enter reading.

Circuit length verification - (Set Cmeter to 200 nF range. Attach Cmeter lead across both bus wires, attach + lead to braid/pigtail.)

Use this formula to verify circuit length matches drawing. Circuit length (Ft/m) = Capacitance (measured in nF) x Capacitance factor [5.2 Ft/nF or 1.6 m/nF]

• Ft = nF x 5.2 Is Cmeter reading within range on the 200 nF scale?

  Yes

  No

  N/A

• Ener nF from capacitance meter.

• Ener calculted circuit lenght.

Power Check

• Test for correct circuit voltage at panel. Measure VAC.

  Yes

  No

  N/A

• Enter reading.

• After heater has been on for 30 minutes, measure circuit current via clamp-on current probe. Measure Amps.

  Yes

  No

  N/A

• Enter reading.

• Confirm ground-fault device functions properly. Press Test button, does device trip?

  Yes

  No

  N/A

• Enter description/explanation of device functionality (wether Pass or Fail).

• If feasible take a picture showing CB/GFI triped.
