Until you've confirmed that a wire is not active, a wire remains active. Don't risk touching any wire during inspection or rewiring, electricity knows no one and even a little electric shock can cause a huge damage to your body.

Always switch off the circuit you want to work on before starting to touch anything. Safety is cheap and essential.
Mistakes are unforgivable in electrical engineering.

Remember, safety first safety always.

What Value Should Your Earthing Give When Tested with an Earth Tester?

When it comes to electrical safety, earthing (or grounding) is one of the most important parts of your electrical system. It’s what keeps you safe by providing a path for fault current to flow directly into the ground — instead of through you or your appliances.

But how do you know if your earthing system is actually effective? That’s where an Earth Tester (or Earth Resistance Tester) comes in. This device measures how well your earthing conducts electrical current into the ground.

👉 Here’s the key:
A good earthing system should have a resistance value as low as possible — typically below 5 ohms for most residential and commercial installations.

• 1 ohm or less is ideal (excellent grounding).

• 5 ohms or below is generally acceptable.

• Above 10 ohms means the earthing is weak and should be improved immediately.

High resistance means your earthing can’t safely carry fault current — which increases the risk of electric shock, appliance damage, or even fire.

So, if you haven’t checked your earthing in a while, this is your reminder: safety isn’t something to assume — it’s something to confirm.
