Last night we had the electric
blanket on - the sleeping cabin
did get below 50 by early AM and my skinny wife is constantly cold.
I do not wear a shirt when sleeping. I kept feeling a strange poking sensation in my chest and stomach area. I thought we had gotten some needles, or sticks in the bed
when we changed out of our hiking clothes. Nope - nothing. But - the sensation stopped when I turned off the electric
This morning I did a bunch of measurements. Ground was either me holding the black probe between my fingers and standing in bare feed on the floor or touching the probe to the mast
2.4 V AC @60 HZ between the outside of the blanket (just laid the red probe on the blanket) and ground & 0.005 V DC
I got that measurement with the blanket turned off or on but the voltage goes to 0 when I unplug the blanket from the thermostat control.
I had always thought an electric blanket was a DC device and the thermostat was an AC/DC converter. I measured 120 V AC @ 60 HZ between the two connectors in the plug
that comes from the thermostat and connects to the blanket - voltage drops to 0 when I turn off the thermostat.
It appears that the blanket runs on 120 V AC which is a scary thought in a boat.
It is hard to think about 120 V coils of wire laying on my chest at night under a port light that drips water
on my head
and chest as it condenses on the cold metal.
What do you know about electric blanket safety
? Are there any more significant shock issues on a boat than on land?
I do not want to debate or even hear about EMF issues - we are well aware of them and I lost
that battle to my wife's cold sleep problems years ago.
We live aboard full time and are looking at many more months of cool nights here.
