Is neutral and ground supposed to have continuity?

Safety ground is continuous through a GFCI. LINE neutral to LOAD neutral is not continuous. LINE hot to LOAD hot is not continuous. As you can see, both hot and neutral go through the mysteryworks of a GFCI device.

Should there be continuity between line and earth?

It should show continuity, because it is finding a current path from the live wire through the wiring to the power transformer, through the transformer to the neutral wire, and to the bond point that connects neutral to ground.

Can you test live and earth?

Initially a 250V direct voltage is applied across the live and neutral wires of the circuit. The test is then carried out between live and earth wires. A low resistance reading indicates something is bridging between the wires, or insulation is damaged, for example by a floorboard nail driven through part of a cable.

What is an earth continuity test?

The earth continuity test is a designed to test the resistance of the protective earth of an appliance and/or the supply lead. It is measured between any accessible earthed parts and the earth pin of the plug.

When applying an earth continuity test to an appliance the earth continuity is found to be 0.18 ohms The likely cause for this higher reading could be?

The way to approach these appliances is generally to omit the earth bond test. After all if no-one including yourself can touch metalwork then neither can a user. They are therefore not likely to receive a shock by touching exposed metalwork that has become live as a result of a breakdown in the insulation.

Is it OK to use ground as neutral?

a ground and a neutral are both wires. unless they’re tied together with other circuits, and not a ‘home run’ back to the panel, there is no difference between the two where they both end up on the same bus bar in the box.

How do you test earth continuity?

The earth continuity test passes a test current along the earth cable from the pin of the plug to the contact point on the appliance. The appliance tester then measures the resistance of that connection. If the earth connection is damaged, non-existent or corroded then the earth resistance reading will increase.

Is the neutral wire earthed?

Commonly the neutral is grounded (earthed) through a bond between the neutral bar and the earth bar. It is common on larger systems to monitor any current flowing through the neutral-to-earth link and use this as the basis for neutral fault protection.
