I go hardware shop to buy abt 90m of Keystone 3C165 at $285/-.
They dont sell by length for the shop I patron. They sell full coil.
Think i will ask Coolserve installers to use for all indoor unit as well.
Actually initially i want to buy for outdoor unit only. As i will set the ampere limit off so my compressor MXY-4A38VA might consume up to 16A max.
But now i worry the wire too thick cannot squeeze into trunking?
any idea how much the shop selling how much for keystone 4C40 and 3C70 per coil?
why you use until 3C165? got until 165 copper stands
if 165 like super over spec leh even 3C70 already a little over kill for control wire
mostly use 4C40 is good enough, we only use 3, got 1 extra wire is for troubleshoot incase need it that why got 4 cords
outdoor condenser unit the wire standard using is 3C70, the house water heater tank i check also using 3C70, the hdb build in concealed wire they using is 1 thick stand of copper wire, the spec i not sure.
most import is the reliable manufacturer using quality copper for the stands, other then that is the outer rubber insulation. if you really want to buy good wire should get those in orange color that use for Outside all weather.
local no sure how much.
