Airbag for lifting Hot tub

[brightspark]

pretend your pinching it and u will have superhuman strength

So me and my lad lifted it without any drama's, used a motorcycle lift to get it the first 18" then just lifted it from there.

The reason I am lifting it is to replace this,
t

The wooden frame at the bottom is rotten all the way round and this has caused the middle of the "tub" to sag by an inch at the front resulting in the tub starting to crack. Shame as the rest of the hottub is still great after 15 years!

So, as Brightspark was watching this, a related question. The mains cable goes into this connector,


I am ******** if I can see how to release the cable, any ideas?

Cheers,

MM

Should be spring terminals normally you push a small screwdriver into the slot above the cable hole and it lifts the terminal so you can remove the cable.

Its when they put them close to the edge of a board then stick the pcb right up against the enclosure you need to be a contortionist with good paper clip manipulating skills.
Sometimes i think designers need to spend at least a week each year on the tools fitting there own products.
My pet hate is control & switchgear so compact you cant wire it up. Or metalclad boxes that you can't fit a nut on once you have punched the knockout because they put it to close to the edge of the box.

Lowering it down is easy put a bin liner in each of four or five cheap plastic buckets, fill them with water and freeze it . adjust the height till you can insert the inverted ice cube at strategic places under the tub , remove all wood & let the cubes melt on their own

Now that is one cunning plan Baldrick!

I plan to remember that for something as yet unknown at some indeterminate time in the future.

look above the live lead screw on the board says GND on it looks like it should be earthed

No thats for earthing add ons. My jacuzzi is almost identical, it has an earth bus bar that you can see at the bottom of the picture and additional ground points for grounding out controller units.

Yep it does, I had to do a double take the first time I saw it on mine.
