Wire size [used on HM6010 terminals]

[Arty1707822014]

Hi, I am wiring Hornby surface point motors on a friends layout, trying to connect into his HM6010 but I need to extend wires, could anyone advise what size wire I need to purchase.

I suggest the minimum sized wire for extending point motors should be 16/0.2mm wire [16 strands of wire @ 0.2mm diameter]. This size wire is compatible with the wiring terminals on the HM6010. Rob [96RAF] is going to ask his HM6010 tech support contact within Hornby what the maximum sized wire is, that is compatible with the HM6010 terminals. Getting this answer back may take a few days.

Initial feedback from Rob's HM6010 tech support person is that the connectors on the HM6010 support the following wire specifications:

AWG 24 to AWG 16 and Cross-sectional areas from 0.2mm² to 1.5mm²

Equipment wire 16/0.2mm and 24/0.2mm fall within those specifications

Equipment wire 32/0.2mm 'on paper' falls within those specs, but needs to be confirmed in practice.

The minimum wire size that can be held securely in place is 7/0.2mm wire which equates to the AWG 24 & 0.2mm² specification.

Thanks , I’ve ordered some rolls of 16AWG wire .

Just to make you aware, AWG16 wire is not the same size as 16/0.2mm wire. AWG16 wire is even thicker than 32/0.2mm wire. It is on the upper size limit of the 'tech support' claimed supported range of the HM6xxx connectors and is very thick indeed.

Thanks for assistance , tried the 16AWG wire and it works fine , now have two HM6010 modules running six signal lights and two point motors with no issues , thank you for your help

Thank you for the feedback on the AWG16 wire suitability. It all adds to the forum knowledge-base.
