Hell I was raised by people who would today be considered "preppers" and I can't stand 'em either.
BUT!
Shit's weird out there and getting weirder. Prepare for logical possibilities like another quarantine or shortages at the shops, and keep your eyes open to things that might cause hardship. Extra freezers are a wonderful idea.
Yup that is exactly what I mean. Thank you.
Now as far as extra Chest Freezers. DO YOUR HOMEWORK.
There are a lot of cheap Chest Freezers floating around. They are cheap because of the high amount of wattage they use for their size.
One of the things I have done with every home I owned is measure my usage of items for every electrical line in the house.
This is the rule of thumb that I use.
Most lines in the US are either 15 AMP (most older homes) or 20 AMP. Most lines in the US are 110/115/120 volt 60hz. Most homes also have a 50AMP 220/240volt line that generally connected to your dryer by itself. You can find this info on your breaker box for the AMPs.
Most appliances have Watts or Amps used.
For simplicity sake 100 watts = 1 AMP.
All major appliances have a starting power and its normal running power.
Starting power is the power that it takes to power up an item. This amount of power is not generally posted on appliances. Most older Appliances have a higher starting power than the more modern ones. Starting power draws more amperage in it's initial start up. A spike you might say.
The reason I am posting this is because when you measure how many appliances can be ran on any given time, most people do not take into count the starting power. This is why many of times people have plugged certain equipment into a line, even though they measure it and suddenly pop a breaker.
My rule of thumb is that on a 20 AMP line I try to make sure that the maximum amount of usage is @ 18 AMP's giving me 2 AMP's for spikes when an appliance turns on. This reduces the chance of popping a breaker by a sudden spike when all appliances are online.
Also make sure that you do the math on how many appliances you can start on the line you have them on. If the appliances you use, in total are us more amperage than what your electrical line is rated for, then make sure you stagger your appliance usage.
And of course remember what appliances are using whatever line they are on. Saves the headaches down the road
