Wire Gauge, Rating - (a reachable "rule of thumb" fee: #forty copper cord has approximately an ohm of resistance for each foot. With the aid of the rule of thumb above, #30 might have an ohm for every ten feet, and #20 an ohm for every one hundred ft.). Energy=modern-day^2 * resistance that means that decreasing the resistance will make your wire less hot. When you have too excessive resistance the cord receives warm, it'd burn off or burn soemthing else, in worst case cause hearth. If the current is small, probable the maximum stressful effect will be that at the give up of the wire the voltage you install will have reduced due to the resistance.
I do not know if a sprinkler in this example manner a fire extinguishing sprinkler or only a gardening sprinkler. If it's miles for safety device i would sincerely get the appropriate wire gauge from the start, to no longer danger that a twisted cord gets "untwisted" so the sprinkler might not be able to perform.
