In these uncertain financial times, DW and I have purchased our future retirement home – will be moving in 10 or so years – meanwhile the property will be rented and we have our first tenant – the real estate agent who sold us the house.
Current SEP is the infamous Federal Pacific 150A model.
We are upgrading the service to a 200A Square-D ASAP.
The neighborhood is all the way out at the end of a penninsula and is subject to frequent power outages.
We are debating the merits of a whole house surge protector which installs in the SEP.
Any experience with a model to fit a Square D?
If the surge protector “blows”, does it shut down the power to the whole house like the plug in model connected to this computer and have to be manually reset? This could be a disaster if it were to blow on a Friday night while we were gone for the weekend – no power to oil furnace, freezers, etc.
Thanks for any insight!

My understanding is that if they "blow" they just turn on or off a light on the unit. Then they need to be replaced.
When they handle a "normal" transient they don't blow -- they just shunt the transient to ground. No reset necessary. It's only when they get hit with a super-duper transient that they blow.
Thanks to all who replied.
Dan - that is the answer I was hoping for - no reset unless the unit is fried, and in that case the appliances would probably be fried also.
JimNever underestimate the value of a sharp pencil or good light.
The unit can fry without the appliance frying, if it "sacrifices" itself to save the appliance. This is why it's good to check the lights on the things occasionally.

I bungled that reply.
Assuming there was no whole house surge suppressor - the appliances would have fried.
Frying the whole house suppressor would be the less expensive alternative.
Thanks again.

Yep.

Some power companies will install a whole house surge suppressor under the meter. They will charge a fee but will cover the deductible on you insurance if you have a surge or lighting strike. Some surge units you can have an electrician install take most surges away and don't shut down. They have a counter on them that lets you know the number of surges they have handled. If a major surge occurs such as a lighting strike on the line the unit has fuse like devices inside that blow. If that occurs the surge was big time. An indicator on the unit will show what is blown and the fuse like devices are replaceable.
That is what we have.
Our power company installed a unit under our meter.
They just pulled out the meter, plugged the surge protector in and then reinstalled the meter.
IIRC they will replace anything that dies as a result of surge that has a motor......

How does your poco charge for thier whole house surge protector?
One shot billing or a monthly fee?
One shot billing or a monthly fee?
Hmmmmmm
DW pays the bills.
So I go hunting. Notice that it isn't per month as it had been in the past.
LOL, DW says we still pay per month. Current bills don't back that up........
So I go through and look in the file, a letter dated Oct 07' which states they are terminating their surge protection service due to the lack of participation. But Alabama Power will at their convenience come and remove the surge protector from the meter base......
By the way, it is still installed as of today.
We "were" paying $5 a month for this insurance and device.
I read the contract and it "had" covered all motor driven appliances and resistance-heat appliances from damaging surges up to $10,000 per incident.
Covered refrigerator, washing machine, dryer, water heater, range, central heating and cooling system, and other motor driven/resistance heat appliances in the home. (from the contract).
Just a rough estimate showed us paying about $420 in total payments for something that was terminated by them. Was it worth it? I don't know, looking back I would almost say no. It was good insurance but now I have nothing to show for it except the satisfaction that if something "did" occur it would have been covered.
Now we need to look at other options like surge strips in the house.
I could have already paid for those............. :-)

About 25 years ago we had a behind-the-meter protector installed. IIRC, we paid for it with a monthly payment (something like $6) for a limited period of time -- a year or 18 months. The unit is still there, though I have no idea how effective it is. I can say we haven't had obvious lightning-caused damage come in on the power lines since it was installed (though we did have one case of damage over the phone line and one case over the TV cable).I've since installed an in-the-panel unit. Belt and suspenders.

We had a similar program offer a few years ago.
I figured up the annual cost and decided I could pay an electrician (and I are one) to put one on the panel.
was just courious how other pocos ran the program.
BTW, they likely won't bother to take it out as long as you stay current with your bills. They will get it if they ever have to do a cut-off. Stay current and it is a free device, you just don't have the insurance anymore.

Well we have never been delinquent.
We are selling the place in the spring, maybe it could go with me? LOL
Put it on the other house.

I think the agreement our power company offers is they will pay the deductible on the home insurance up to $1000.00. This is if the surge comes through any source.
Ours wouldn't cover every source, just the power side of the house.
No phone, cable, etc.....
If lightening hit and came through your cable or phone line I wouldn't expect a power company to be responsible for something that was beyond their control. IMO.

I can understand the reasoning. Our Electric Utility covers no matter if the surge comes in the phone line, cable, ect. That is one of there selling points.
That is awesome they do that......
I'd keep that protection if I had it offered here.

I work for a utility company. We have surge protection on a 3500 amp service to our main data center, and it has never "blown". It is a little beefier version than your typical whole house model, but made the same basic way. I think the last time I looked it had counted close to 100 surges.
I think you would be safe with installing one and not worrying about it taking out the service to the house while you are away.
What size are these things? Where do they get installed? If one has a finsihed wall and the panel recessed, can they still be installed?
One style installs like a double-pole (240V) breaker. Another style installs on a knock-out, kind of like a doorbell transformer. Then of course there's the behind-the-meter style.I have a behind-the-meter unit that I think is an old (slow) gas discharge type, and a double-pole-breaker style unit in our Square-D panel.

With the breaker-style units, they're supposed to be installed in the top-most slot, nearest the main. But I couldn't do that easily so I put ours in an available slot near the bottom. You lose some effectiveness that way, but it still gives you maybe 90% of the protection you'd get the "right" way.It's still a good idea to have point-of-use protectors for sensitive equipment.I've had equipment damaged due to surges over the phone line and over the TV cable (before I installed surge protectors on those), but never due to power line surges, that I've been able to tell.

You can also just install surge breakers specificly for rooms like the office or living room with the expensive electronics.

When you install your new panel be sure the ground electrode system is good. I would drive another rod anyway and connect it in addition to what you have. Then be sure all of the providers are using the same electrode system your panel uses and that they have entry protectors. There should be protectors on every wire coming into your house, all connected to the ground electrode system.
If you can get everyone on the same ground and stop the surges at the entry point your stuff inside will last a lot longer. I would still have point of use protectors, protecting all inputs at the TV, computers and any phone with a power cord.
