    110V air purifier with a 100-240V adapter

    I purchased an air purifier printed 110V. It has a power adapter of 100-240V. Can I use the air purifier with a power supply of 220-240V? Is the adapter also a converter or transformer? I’m really confused.

    My niece has a 2004 Mazda Tribute with a strange air bag light problem. She can make a 40 mile round trip without the light coming on if there are no high load devices on, but if she turns on the heater or lights the air bag light comes on a few seconds later. To me this means the problem is due...

    Consumer unit: which comes first?

    greetings. Just a quick question about switch order. Should the main circuit breaker be wired in first before the main switch, or is the main switch always first in line from the supply feed? Thanks, Gary
