I spent all day at the office/studio today, mostly making up adapter cords for the various uninterruptible power supplies (UPS) so they can be put into service quickly, as needed in different places. All the UPS units used here are 110 volts only.

The large UPSs use huge 60 amp plugs for both input and output, but the smaller spare UPS use 30 amp twist locks for the input and standard 110 volt grounded plugs on the back for output. I installed a flexible extension coming out to the bottom of the circuit breaker box that feeds the large UPSs. A 30 amp breaker was installed to feed this cord and a 30 amp receptacle was connected to the other.

I then made up another extension with a standard 20 amp 110 volt grounded plug on one end to plug into the back of the smaller UPS. The other end has been stripped back to connect into either of the circuit panels that are fed by the big UPSs.

If one of the large UPS fails, all that needs to be done is remove the 60 amp cord, punch out one of the small knockouts in the bottom of its panel, pull the wires through the hole until the clamp is seated, tighten the lock nut and attach the wires (load, neutral and ground) in the right places. Hopefully this can be done is less than 5 minutes.

I would have preferred to make an extension with a standard 20 amp 110 volt grounded plug on one end and a 60 amp receptacle on the other end to mate with the current cord that plugs into the back of the large UPS which supplies the circuit breaker panel attached to its output. Unfortunately there are no 60 amp receptacles on Bonaire and to buy one from the U.S. would cost about $70, plus the time and expense to get it here. If by rare chance, I can find a surplus one somewhere when back in the U.S., I might try to get it for this application.

When I arrived home for lunch today, Virginia pointed out there was a baby gecko, less than two inches long, in the corner of the dining room and asked me to relocate it outside. The picture that we took of it was not in good focus, otherwise we would have included it here.

This evening we went for our regular swim and cooled off nicely. Hopefully the hot days in the mid 90Fs that we had when we came are past. Now the highs seem to be in the upper 80s cooling into the lower 80s at night. Yesterday morning the temperature got down to 73F during the rain. The lowest we have seen yet!
