Broken mains cable right of way

Recommended Posts

Greetings,

our company (a wellness center open to the public) is facing a problem due to a broken mains cable running from the transformer to the electrical panel (3 phase).

The cable is running mostly underground and is passing by a property we only partially rent (a condominium parking lot).

We asked the condominium committee the authorization to make an urgent maintenance work (break the concrete where the cable is running to replace the cable) since we are out of power but they are not answering.

We should have the right of way since the cable is already running in the exact same place where the work is needed but no written documents confirming it.

What can we do? Given the urgency can we start the work without a previous written authorization granted that we will preserve the parking operations and the area restoration?

It is downstream.

 

PEA already checked and said that it is up to us to replace the cable, no advice given on how to proceed from the legal point of view

And assuming you're replacing all the wire anyway, you can always run it above ground until you get the digging done.

 

Be sure to run block it such that it does not get damaged getting run over...

With RichCor on this, a decent cable checker can tell you to the centimetre how far away the problem is (short or open)

And if it has to be replaced and is in a conduit, got with Yellowtail's suggestion, no need to open up anything, just pull a fresh one using the old one, might need a little 'persuasion'

 

Here are some samples of the test equipment you're looking for:

Thanks everyone! A lot of useful information.

One last question: do you know someone in Phuket that has the required equipment to check where the cable is broken or does PEA offer that kind of service?

I doubt PEA will want to do it even if they have the tech.  Can you just pull it out?

Edit:  How do you know it's broken?  Check for loose connections.  Only 1 phase down or all?

Excellent question. It's odd that all 3 phases would be down, unless the building is utilizing them as 3 single-phase and the Neutral is down.

 

I'm assuming the OP has had an electrician in and they've verified working service at the meter, with no meter activity, and little or no working service at the building's CU Breaker Box?

Yes, PEA can for a fee. Nothing more than a Varley Loop Test, or approved equivalence.

Don't understand your perception that the Condominium is responsible for your cable routing. Seems there's some missing historical data.

Only 1 phase is working. We checked all the connections and and tried to pull the cable out but it is stuck somewhere.

We checked with the juristic person manager the title deeds and the cable is running under condominium common areas (a parking lot).

The juristic person manager is insisting that without committee approval we can’t do anything else the pulling out the cable and replace it but no drilling work whatsoever.

We checked with the previous company owners and they told us they had only a verbal agreement with the condominium for the right of way so no way to enforce it.

If PEA will not be able to find where the problem is or to pull out the cable we will most likely drill without permission and then pay for compensation as required by civil law since we have no other way

A really stupid question before you start digging.

 

Have you verified that the dead phases are actually OK at the meter?

 

It wouldn't be the first time that meter connections have come adrift.
