Re: [MBZ] Running freezers on extension cord
12ga is 20 amp wire, but voltage drop at 20A might be excessive for a 100' run. I'd plug the freezers in one at a time because the voltage drop if they start simultaneously might not be healthy for the compressor motors. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] Running freezers on extension cord
I have a chest freezer in my basement that my parents bought from Sears in the late 70s, probably. It's still running, cold as ever. I really need to get down to the Odon Locker and buy some beef for the winter.

Re: [MBZ] Running freezers on extension cord
All they'd need: One PIC, or other sub-$ microcontroller. A capacitively-coupled power supply, a couple of isolation diodes, a zener diode and a resistor, a rechargeable coin cell suitable for CV charging, a thermistor, a beeper, and a switch. What do you think that would cost in Chindustrial quantities? -- Jim > On Sep 2, 2022, at 6:42 PM, OK Don via Mercedes wrote: > > What Jim said ! > > On Fri, Sep 2, 2022 at 8:34 PM Jim Cathey via Mercedes < > mercedes@okiebenz.com> wrote: > >> >> It's ridiculous that they can't spend $3 these days to put in a stock >> freezer alarm, one that beeps loudly if it's unplugged, or if it goes >> above freezing inside.

I'm in the middle of a multi-stage bleach/ozone recovery of our garage freezer that got unplugged by accident. It's going well, the initial stages were... unpleasant. It's ridiculous that they can't spend $3 these days to put in a stock freezer alarm, one that beeps loudly if it's unplugged, or if it goes above freezing inside. What's more, you can't even buy something that does this.

Re: [MBZ] Running freezers on extension cord
Like my Kenmore upright manual defrost freezer I just sold earlier this year?

Re: [MBZ] Running freezers on extension cord
Starting surge current is rarely rated, but 2x might be a fairly safe bet. These newer, more energy-efficient freezers are sized smaller, but they run on a greater duty cycle.

Re: [MBZ] Running freezers on extension cord
Heavier wire is better. You can get an extension cord for a travel trailer that is good for 30 amps so likely #10 wire. Just a guess, but I think if you use a heavier cord, your freezers will likely last longer.

Re: [MBZ] Running freezers on extension cord
No, other than the inrush current when the compressors start. I’m sure it’s more than 4 amps. -D > On Sep 2, 2022, at 2:01 PM, Kaleb Striplin via Mercedes > wrote: > > So I bought this enclosed trailer for the spouse and bought 2 of the large > chest freezers at lowes to put in the trailer to use while it is parked at > events.

Re: [MBZ] Running freezers on extension cord
Starting current for a bit might be higher but running current can be low. You should be good. --FT Sent from iFōn > On Sep 2, 2022, at 5:01 PM, Kaleb Striplin via Mercedes > wrote: > > So I bought this enclosed trailer for the spouse and bought 2 of the large > chest freezers at lowes to put in the trailer to use while it is parked at > events.
