In these examples, shouldn't the single wire that is spliced out to multiple others be a larger diameter? (For current capacity reasons as explained in earlier lessons)
Or is the current in a 5V sensor supply circuit so small that it can be spliced out to the various sensors with the same gauge wire?
The latter -- sensor grounds and power requiements (even combined) are not anywhere near the wire limits.
Yup, the latter.
If we assume an average current of 50mA per sensor, then a single 22awg wire could handle 100 sensors.
Got it thanks gents.
Follow up question -
Is it acceptable to combine a splice with a terminal? For example:
option 1, single wire terminated with a connector pin which is then spliced into 2 wires,
option 2, instead terminating both wires into a larger capacity pin that is still compatible with the connector.
I ask this question as I'm curious whether it could save a splice for the relays where pins 86 and 30 are in parallel, and instead terminate both trigger and feeder wire into pin 30 (the image attached might make it clearer)

Yes you can do that. That is my typical method when wiring a relay.
Awesome thankyou.
