You can use #6 copper. It's technically rated for 55 amps but the rules in the code book (240.4(B) allows you to use it for a 60 amp disconnect.
Wire size depends on amps. Use #10 for 30a. #8 for 40 or 50a. #6 for 60a.
A #6 copper wire with an insulation factor of 75 or 90 degrees C is rated at 65 amps.
A 60A breaker will protect a very large conductor indeed, much larger than an ordinary household water heater would need. Many houses only have a single 60A main fuse!It would be pointless and dangerous to use a 60A breaker to protect an electrical cable (and appliance) rated for, say, 30 amps. So, you will need to find out the name-plate rating on the water heater before you burn something down.
SOOJW is limited to 300 volts and should not be used on 480 volts
For runs under 75ft 4 gauge wire is recommended. For runs over 75ft consult a wire size calculator. Remember that the total circuit length is twice your run. (length of Hot + length of Neutral) Don't divide your run length by 2.
Use 6/3 Romex protected by a 60A breaker. You'll never miss the other 10A.
Wire size depends on amps. Use #10 for 30a. #8 for 40 or 50a. #6 for 60a.
There is no reset on the disconnect, you will need to check the fuse's at the disconnect and replace the on that is bad. But most likely if you blew a 60 amp fuse you have a short somewhere, check your termanals at the compressor to see if the compressor went to ground.
480V, 3 phase, 60A means 60A flows for each phase? or 60A flows at neutral.

sb 60a
10 kW at 220v will use 45.45 Amps. I'd recommend a 60A circuit, with a 60A breaker, but the heater or electric furnace should have "maximum fuse amps" rated on its nameplate. Above all, neverconnect wiring to a breaker that is rated higher than the maximum current capacity of the wire. In the case of 60A, use #6 AWG wire.The HVAC Veteran
The main fuses protect the feeder lines from the electric company's feed to the main panel for the maximum ampacity rating of the wire. So depending on the size of the incoming tails nothing is gained by reducing the main supplier's cut-out fuse rating to 60A or 40A.
More than likely you'll have to get a new panel with larger wire. The power company may have to come in and upsize their wire to your house as well. And you'll have to get a larger meter can. Fun, isn't it? :)
Its not recommended because your new main breaker will allow up to 100 amps and your old wire can only safely handle 60amps. If you put a 60amp main breaker in the new box, that would be acceptable. No, it is perfectly safe. Because the box is overrated, there is no problem. If the box is the main panel, and not a subpanel, install a 60A main breaker so you cannot overload your service. If it is a subpanel this 60A breaker should be in the main panel.
According to a book dated 2001, the 60 or 60a run as follows: 60> exc.$400-VG>$250-good>$200- Fair>$150-poor>$100 60a>exc.$400-VG>$300-good>$250-fair>$150-poor>$100 the 60 started production in 1931 the 60a started in 1933; it was the same rifle as the 60, but in a target configuration. The 60 was disc. in 1934 with about 166,000 rifles sold. the 60a was disc. in 1939 after only selling about 6,100 rifles.
