Looking for ideas on where/how folks are bringing mains power to the LR4?
For my LR3, I built a 2-gang metal box with a SSR driving one outlet, and full-time power on the other outlet, with a regular light switch controlling power to the entire box. I’m inclined to use this same box on the LR4, but mounted directly on the gantry (my previous LR3 was smaller, so the box was mounted to the side of my table). The only thing I’ll need to change is the cable that brings power to the box - it’s far too stiff to be riding in a drag chain on the Y axis; I’ll get some SJEOOW cord instead (or at least, I think that’s the stuff I need).
If you’ve done something similar (and I searched the best I could but came up empty), please post a photo or a link.
Did 100% silicone blob various 120VAC connectors. Curious what pro electrical folks here think of that option?
Personally, when possible, I almost always round hook mains wiring with needle nose pliers. Rotating same direction screw fastens, typically clockwise. Takes more time, but I know the wire is less likely to work free.
Thanks for all the concern. The ground is just fine and the uncovered lugs are tucked away inside a junction box, next to lots of other uncovered lugs.
My existing box is too big to be mounted on the LR4 gantry, so I’m just going to get some 14/4 SJEOOW or similar cable and install a single gang outlet on the LR4 - one outlet switched for the router and the other always on to go to the Jackpot power supply. That’ll make for one power cable and the SSR driver wire to be routed in the drag chain, should work out well.
Was really looking to see what other people have done. Post up some photos, folks!
From an electrical engineering perspective, it seems fine.
But electricians (and the building code) has different goals. They aim to make rules that are easy to follow (so people actually follow them correctly). I would not be surprised if silicone blobs were a no-no because they are too hard to do correctly or there is some variability in silicone.
It’s a long and rambling thread so you’ll have to skim a lot of it to find the detailsi you are looking for, but…
I treated my LR3 as an “appliance” - the mains power is built in to the table with an Emergency stop wired between that and the IEC female plug which the machine connects to.
The machine has a lead “hard wired” from a box on board which splits power to the 12v power supply and another IEC female plug for the router.
It’s simpler than it sounds, the router can be removed at any time, and the whole LR3 can also be simply unplugged from the table if necessary.
