Use of GFCI

I have my Alta. electrical code book somewhere but 8 devices which includes lights outlets switches etc. seems to ring a bell which of course would be one of the 8.

You may be refering to circuiting loading which is typically 12 outlets (1A/oulet) on a 15A breaker unless the load in known (switches not included as there is no load from a switch).

I did a quick look thru the CEC and could not find a limit on the number of receptacles that a GFI protects therefore it is limited by the CEC circuiting loading. There may be a spec from the manufacture perhaps.

Like he said and there is no load on a switch.

You can also get breakers that are GFI protected. It would be great for multiple tanks that run on the same circuit . Cost is considerabley more than a regular breaker, but a small price to pay for a possible freak accident

The big problem with this is if one item trips the gfi everything shuts down

My house it only two wire, it is 100 Amp copper will a GFI plug still work on with no ground. If so I think I will put them on all my tanks, I have little hands around here I don't want them to get in a tank with live electricity in it.

It works. It's also highly recommended for ungrounded systems as you don't have the benefit of bonding. The only hurdle is the cost.
