i have a 110v hoist ,courtesy of @Welderpaul ,and need to make up an extension cable so it can travel along the runway,the feed cable to the motor is 11mm o/d,with a large size plug,what size cable should I order? Thanks.
Motor probably has a plate on it. Look for the rating.
As barking Mat says I’d say 2.5mm would probably work but just check what the rating is first. I will be doing similar in my garage when done, make sure you buy some decent cable. That blue or yellow cable is rubbish. I have some 6mm cable branded superflex for a welding extension cable and that’s really flexabile and sturdy.
Where would we be without @brightspark ?2.5mm rubber flex will cover it
