Is there any GFCI with a rating of 220V? We are not using 110V anymore.

on Feb 2, 2017

There are 120/240V GFCI devices, such as the Eaton/Westinghouse CH220GF (Cutler-Hammer GFCB220), if that's what you mean. There is also the LineGard series for inline GFCI, including 240VAC with pigtails or L6-30 plug/receptacles (at gfcistore.com).

There is. I still remember that we used these and the brand name was
Panasonic, but the price then was more or less $3,000 to $3,500 Php each
piece.

Did you know that if you install a light switch upside-down it says "NO"?
You will know you did it wrong!

If it's a 3-way switch it's "maybe" and "maybe not".

I'm not aware of any U.S. manufactured GFCI receptacles rated for 220V since that's not an NEC requirement. However, you can get an IEC 60320 socket with a 10mA trip rating that is rated for operation at 230V. Kopp makes a schuko outlet with a 10mA RCD also.

GFCI isn't really measuring "electrons," but rather the corresponding charges (moving via the metallic conductors) and the resulting EM fields generated in each direction by the two conductors.

Am I wrong that all pictures of the receptacles are upside down, with the ground at the bottom?

That switch also says 'ffo'. Learned that one in apprentice school. Also loved the weatherproof in-use cover on the outside installation in the first picture. Where is the Electrical inspector, other than drinking coffee with the cops?

Grounds on receptacles can be up or down. There is no Code rule on this topic. It may be required on a specific set of drawings on certain jobs.

On image #3, where it says, "two small-appliance branch circuits" does that mean two individually protected circuits from the panel? And if there is only one outlet (small kitchen) does each socket in a dual outlet need to be on its own breaker?

Can anyone give a diagram or say how to make the connections of electronic grounding and electrical System Grounding that can minimize electro-magnetic interference? Thanks in advance for your help.
