A new fan will work perfectlyh well with the old fashioned electromechanical relays. It will work perfectly well with no ground, just hot and neutral (positive and negative if you really insist although it will not work with real DC positive and negative and might not work with modern solid state relays).

The significance of being properlyh grounded is so that if someone should reach up and touch any metallic parts, it is much safer that way.

Separtely routed ground wires (grounding conductors) can be retrofitted to an existing electrical system and still be code compliant.

I thought that was the case, but I didn't trust my memory or previous experience

I'll check after I install ...

Ceiling fan up and running w/o issue - thanks for the guidance

Ceiling fans not working

I have the low voltage electric system common in houses built in the 50s/60s. A royal pain the rear - no clue why they did this
Anyway - my bathrooms fans have both stopped working (and heated lamps) and ive traced the culprit back to the Relay Box in the crawl space - any idea how to proceed and find out if its a dodgy relay ?

The quickest way, is to swap over with a known working relay.

Not sure what kind of relays you have but I've had good luck with a loop of solid wire about 6" long. Strip the ends just 1/4". Short out the relay you suspect is the correct one. It's basically a switch. Then you would have to check to see if voltage is going to the relay when the switch is being held on or off. They are latching relays if they used GE relays. Not sure if GE RR7 or RR8's are available anymore but I think we found RR8's were replacements.

Just becarefull the RR7 et RR8's are simauir but not the RR5 which it is a non latching while the RR7 et RR8 is latching so to make sure you have correct one you should heard a short buzzing sound with a clunk which it will move a cam inside to either on or off postion.

But they are still avaibale to get it but I feel that the big box store may not stock this so run by the electrical supply centre this will be next best bet to find them.
