New 3-phase service


Recommended Posts


Yes , neutral is likely grounded every 3rd pole.  

 

The ground will be a separate wire running down the pole to ground or as I have seen in some older installations, joined to the protruding rebar at the top of the pole.  Of course you will still be providing your local earth.

I am thinking of buying a new home and would like to upgrade the power to three-phase.

 

Looking at the photo below, does it look like 3-phase is available?

Yes, it's available. 

 

Send a photo of the electricity meter. 

You may already have 3phase.

Yup, 3-phase supply is available.

 

Ground is not supplied by the MEA/PEA although the neutral is usually grounded every 3rd pole of so for a TNC-S (MEN) system.

 

It is worth talking to the local PEA office to check what they will actually provide.

@Yellowtail . I've got a 3 phase supply to my house.

I  am only using 3 phase multipoint instant water heaters. 

I treat the 3 phase supply as 3 single phases.

Give us a yell if I can help.

Thanks, I want three-phase for air conditioning and a few old machine tools I have.
