There are lots of different formulations, and lots of additives, so I think no one can give good general advice. You will need to look up the specs of each individual filament, or ask the manufacturers.
Or do tests yourself: cut off a piece of both filaments and keep them in a flame. And see how it burns and how the fire propagates, or does it extinguish by itself? Also melt it with a very hot soldering iron, and see if it catches flame? Of course do this in a safe environment, e.g. outside, or in a kitchen in a metal sink, with plenty of water available. And with safety glasses.
Thanks for all the replies. I did some test on my materials and the end results are similar to what this person did in youtube. Seems like PETG is really hard to catch fire compared to ABS. But I rarely see PET being used in electrical enclosure, maybe of its lower melting point. I heard that PC is a better material for engineering application, but I guess PC will be even harder to print as my ABS warping problem is already hard to solve. I will try the ABS+ material in my next project to see if it can improve on warping.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

There are flame retardant materials for 3D printing. I would would take a look at these, just to be on the safe side.
