Effects of Bad Buried Electrical Lines on My Home

10/02/2014 10:54 AM

In coastal community in NC, USA. New single family home - moved in 3 months ago. Woke up to dimmed lighting, non-working appliances, slow turning exhaust fans, etc. Found out that the sewer company shoveled the buried electrical lines during the building process and they have been degrading/corroding over the past 5 months. Minimal power one morning alerted us of the problem. Brown out type conditions. No reading on interior outlets.

1. How much life did I just lose on all of my brand new appliances: Refrigerator, Washer, Dryer, Stove, Dishwasher?

2. How much damage could there be to my HVAC unit that has been running with less power over the past 3 months we have been living here? It's a 3 story 2800 sq. ft. home with a thermostat on every level.

Asking because I don't know and am going to approach the builder about extending our warranties due to delivering a home with a degraded power supply.

Thanks!

Shehla

It's really impossible to quantify the "how much life" question, there are WAY too many variables involved beside just the low voltage conditions. Certainly there likely is damage in some devices, but determining how much is the problem. Step one is to gather and read all of the owner's manuals on these appliances, paying close attention to what it says about voltage tolerances. I find it easier now to download pdf copies of them and do keyword searches, saves a lot of time.

Going down your list:

  • Exhaust fans; probably Shaded Pole or PSC motors, no likely significant damage, just poor performance, as you witnessed.
  • Refrigerator; maybe damage to the hermetically sealed compressor motor, not much else that could go bad, but I would ask for them to extend a warranty for that at the very least.
  • Washer, not likely to have been damaged if it was one of the newer 'HE" (High Efficiency" washers, because it will have a switch mode power supply for the controls, which will accept a very wide input range, and an ECM (Electronically Commutated Motor) or a 3 phase motor driven by a phase converting VFD, either of which would have just adjusted the performance for the lower voltage. That means your cycles would have operated at lower speeds, so your clothes maybe didn't get as clean as possible or took longer to run through the cycles, it all depends on how the mfr designed it to deal with low voltage conditions.
  • Dryer; same as above on the motor, if it is an electric dryer, your heater elements just didn't get as hot, so everything took longer. If it is a gas dryer, not even that.
  • Stove / oven; assuming electric, no harm, but again, less heat.
  • Dishwasher; not sure, but I think many of them have gone to ECM or VFD motors now too, and the water heater elements, same as the dryer and stove, no harm.
  • TVs however, maybe. Many flat screen LED / LCD units now have low voltage protection cutouts, so you would not have noticed unless the TV failed to turn on (that's the way mine is). Plasma might be the same. But if it was a cheaper version that did not have the cutout, or an older CRT set, it may be toast in short order.

Aside from the electrical issues, there are companies that will provide aftermarket extended warranties on appliances, I bought one for my aging mother (so that I don't have to make the trip to fix her washer or dryer). I would not do it for myself, and they are a pain to deal with, but if you can convince the contractor to pay for it, might be a good option. That said, I have worked for a lot of contractors doing sewer work, most of them have a "hold harmless" clause in their contract with the service district saying they will not be responsible for collateral damage that is not the direct result of negligence. So be prepared that their first line of defense will be for YOU to prove the damage was the result of NEGLIGENCE, not just an accident. They will, by the way, have a lawyer and an insurance carrier with deep pockets to pay for him...

I don't think you can get a definitive answer on the potential damage as there are too many other variables that matter.

I guess the answer really boils down to whatever an attorney can sell the other party as that is what it ultimately shakes down to be.

You have a weak case....It's not likely that any damage can be proven or in fact that any occurred.....otherwise we would not be having this conversation....the motors all have overload protection....Unless you were monitoring and recording the incoming voltage, you have no proof of lack of reliable service....Even if you had that you would have to have documentation from the contractor that did the repair proving that it was caused by the building contractor....and then you would need proof from an appliance repair tech that the appliances have been damaged....none of these would be easy to obtain....Without the proper proof of damages, you only have hysterical accusations...

I had the site supervisor here with the energy company who dug up my yard and handed him the pieces of electric line there had the shovel marks in it. There was a discussion between the company and the builder about who gets the bill and the builder accepted responsibility. Wouldn't that be enough proof to at least have a discussion?

Not without proof of damage to your appliance....I mean you can give it a try, you've got nothing to lose....but you can't really press the issue...If you get anything from the builder, remember it's useless without documentation.....e-mail, text message, or written documentation, but something you can hold in your hand....

Not what you are asking but:

1) Is everything safe now? You don't want a life of equipment issue to turn into a life of people (or pets) issue.

2) Are you still using bad power in your house? I would suggest turning off the main breaker until everything is correct and safe.

Yes. Everything is safe now. First thing I did in the morning was turn off the breakers cuz the power company told me to. I called them first thinking there was a power outage or partial. The breakers remained off until the power company fixed the problem. Thank you for thinking safety first. :)

The low-voltage operation time period was short; it's quite possible, even likely, that you suffered no degradation or shortened life at all. I think that should be your first assumption until you learn otherwise.

Your first goal should be to insure your that AC line is fully up to snuff, I suggest you purchase a multimeter so you can take voltage measurements, e.g., 120V, at the wall outlets, etc., and monitor the situation. Keep in mind that you have two sets of 120V circuits in your house. The circuits alternate between every other breaker on each side of your breaker panel (that's so a double breaker can grab 240V for a hot water heater, etc.). Anyway, you'll want to identify a few on each side and check both circuits.

You may or may not have a problem, but it's hard to look in to the future. Your first step is to approach the builder and see what his response is. If he denies responsibility then unfortunately you're going to need the services of a local professional engineer to assess the damage and its possible long term effects, and then a lawyer if the builder is still unresponsive. You might also check with your homeowners insurance carrier, you may have coverage and they'll chase the builder on your behalf. Keep good records of every conversation.

Most new homes have some type of warranty. Look at that before any thing else. There maybe something in it that will rectify any issues you have. The HVAC would be covered under the warranty if sold with the house.

sorry for the bad lucklow voltage is hard on motors...assuming they were in service. an idle motor is no problem. I'd be moat worried about AC and fridge compressors, most everything else should be fine. an electrician and a megger check would confirm degraded insulation on motors

Typical of Americas claim culture. How much can I get for damage that hasn't been proved.

Dear Anonymous,

Not sure who you are addressing. I didn't ask for any money, nor have I mentioned filing a lawsuit. I had a home built and I have paid for a certain type of product. There is nothing wrong with expecting it to be 100% for the 1st year. That accountability has nothing to do with Americas claim culture. I'm grateful that this site has posters who pointed me, a mother of two with NO electrical background, into a positive direction to take care of my property.

To ask for an extended warranty constitutes asking for money.

Is the equipment working correctly now the supply has been restored?
Is there any sign of poor performance? If there is and it can be proved as been due to the supply fault then you're entitled to some recompense.

The claim has to be proved, it can't be based on supposition.

At best you could claim for inconvenience.

This sounds like perfect case for Judge Judy.
