Bundling of cable (what you are correctly doing) reduces the heat dissipation ability of the cable, so some safety component ought to be considered (ie do not use a 2x 20 awg cable for dc energy if the software is power and requires a minimum or unique 17 awg, however if the requirement is greater than 17 awg however less than 20 awg it is probably adequate, or if heat isn't normally an problem, which includes loudspeaker cable, warmness dissipation problems may be overlooked). Again, all depending on utility. (a available "rule of thumb" price: #40 copper cord has approximately an ohm of resistance for every foot. Through the guideline above, #30 could have an ohm for each ten toes, and #20 an ohm for every one hundred ft.).
I don't know if a sprinkler in this situation method a hearth extinguishing sprinkler or just a gardening sprinkler. If it is for safety equipment i'd truely get the suitable cord gauge from the start, to not chance that a twisted twine gets "untwisted" so the sprinkler might not be capable of perform. In case you twist two wires together, each could bring 1/2 the contemporary, so that you'd "efficiently increase the gauge." American twine gauges move down through approximately 10 for every issue of ten in go-sectional location. In case you had ten #20 wires related in parallel, they may carry as lots electricity as one #10 cord. With #20 wires, you'd have the equal of 1 #17 cord.
