WARNING to CPAP Users: PREPARE for the Unexpected - When the power goes out

Quote:Its very easy to screw up and cause a backfeed situation

As an electrician this can only happen if you hook this generator up WHOLE HOUSE wrong and that would be through your main power panel. If you set it up in your garage - make darn sure of good ventilation, plug your output through a good qaulity surge protector, run you essentials off that s.p. (and as an electrician I have to tell you that you are not suppose to hook any thing up using an extention cord!!! - my disclaimer.) When the power comes back on you do not run the risk of electrocuting any line worker.

And all those who read this should give those guys a big hug and thank you. You do not realize what they go through to get your power back on!!! Please do not P & Moan if it isn't on within 2 minutes. They get called out in the middle of the night, drive to there equipment, climb the poles, remove the down trees, etc; etc; all in some very not so pleasant weather conditions. Congrats Well-done Amazing Good-work Thanks

I can''t say enough. You line workers are my hero's. You take a lot of crap that ain't your fault. Give yourself and every other line worker a big salute, hats off, hug, hand shake, and thanks you from me!!!

I have my furnace, hot water heater and a few outlets and lights in the house that are working. My machine has a alarm on it, when the electricity goes off, it sounds off.

Don't remember the theory of why that is, but "I" would NOT do it.
That is what whole house generators are made for.

Don't want to sound like Respiratory Chip, but in this instance, this should be left to the experts.

This is what Goofy was talking about. Unless Papa Goat knows what he's doing, or a QUALIFIED electricician does this I would disconnect it imediately if not sooner. The backfeed can injur some one.

.05 mill amps across you heart and you can die!!!

A Note Concerning The Japanese Earthquake Today

As we think and pray for the survivors in the massive Japanese earthquake and tsunami, it gives us reason to pause this week and think about our own preparedness.

Many in Japan will be without electrical power for weeks. They will be without clean drinking water for weeks. They will be without telephones for weeks. They will be without Internet for weeks. They will be without normal banking operations for weeks. No way to purchase goods, foods and medicines. They will be struggling to return to any sort of normality for a long, long time.

Even if you're not in a high-risk earthquake area, a coastal area, or another high-risk zone, trust me, no matter where you live, it can happen to you. The emergency can be national, state-wide, county-wide, city-wide or only in your neighborhood. It can be just you personally and those who live with you.

There are many fault lines in the U.S., even here where I live in the Midwest. Who knows, whether it might be a biological, nuclear or chemical Terrorist attack - Nuclear power station emergency and associated radiation risk - weather related disasters such as floods, tornadoes or hurricanes, fires, etc. The prepared person stands a much better chance of survival.

Do have a backup plan for electricity? Heat? Water? Food? Shelter?

I again plead for our members to seriously consider personal preparedness:

Are YOU prepared?

Thanks for listening.

At least once every human should have to fight for his life, to teach him that milk does not come from supermarkets, that safety does not come from policemen, that news is not something that happens to other people. -- Author Unknown

Preparation through education is less costly than learning through tragedy. --Max Mayfield, Director National Hurricane Center

Remember; when disaster strikes, the time to prepare has passed. -- Steven Cyros

It happens around here every time there's a big power outage and whole families (or just the kids) die.

This is a good way to earn a Darwin award.

NEVER FEED YOUR HOUSE POWER WITH A GENERATOR unless you have a properly wired automatic transfer switch. Even if you think you know how to cut off power at the main breaker. You could kill a utility worker. The utility companies have threatened to press manslaughter chargers against people who do this.

If you don't get a properly wired system, use extension cords and plug individual devices into them.

archangle Wrote:Battery management is tricky.

Many people have felt comfortable with their backup battery systems only to find that when they need them, they look like they're charged, but don't actually hold enough charge to work well. Batteries that have sat for a long time tend to become weak. They may show a good voltage, but when you try to use them, they don't have much charge. Think of what happens when a car battery dies. You give it a full charge, but when you try to crank the car, and it turns a few times and dies.

A "trickle charger" sounds like the correct answer, but a lot of "trickle chargers" will slowly ruin your battery if you leave it connected all the time.

I've found the Schumacher model SE-1-12S charger doesn't eat my batteries like a lot of them do. I've probably got about 20 accumulated "battery years" with one of these and haven't had any battery problems. They will take a long time to recharge the battery if it's run down, but they keep it in good shape. For an extra layer of protection, get a 1 week on/off light timer and program it for about 8 hours on time per week. This will keep the battery charged unless it gets discharged. If it gets discharged turn the charger on full time for a week or so.

You should run something off the battery once a year or so and be sure that it's actually holding a charge. Batteries eventually lose their capability to hold a charge, even if you do everything right.

Even on a deep cycle marine battery, DO NOT run it all the way down unnecessarily. It's always harmful to any lead acid battery to deep cycle it. It's just that marine batteries get damaged a little less than starter batteries.

Always put a fuse in the power lead AT THE BATTERY.

If you use other types of batteries or chargers, make a schedule and charge them once a month or so. Lots of people have backup batteries but forget to charge them and find they're useless when an emergency happens.

The Japanese experience certainly got me thinking! I have two marine batteries and a smaller gel battery, DC adapter and cables. The batteries are periodically trickle charged. I do have older CPAP units for backup, lots of camping gear, a supply of food, and a hunting rifle. I thought of getting a generator but realize fuel would quickly become unavailable. What else to do? Went to Costco and bought a solar panel kit, 55 Watts. If there is enough light, I can charge batteries. I think that this is about all I can do! Living in an earthquake zone, one hopes for good luck that the house stands or, at least, does not come down with your family in it!

Be sure to follow proper jump start procedures for the car battery. Especially be sure to make the last ground connection to the frame of the car, not the battery, and disconnect that connection first.
