Thanks Warra,
What you've stated is what my research has shown. In terms of capacity they go from red, blue and yellow. With yellow being the highest/biggest. These are usually coated in pvc and whilst considered insulated they are not fully insulated (which requires coverage of the entire terminal) as you mentioned. Fully inssulated/covered terminal also appear to have a higher temperature rating and what Ill be using to connect my elements to the power lead, given they will be enclosed in the element guard and may be exposed to higher temp.
For those that are interested I have attached a page from a catalogue that explains the ratings etec and have also inclued a link to the catalogue (about 10 pages) which included further specific details.
Insulated Crimp terminals .pdf
The link to the catalogue is
http://www.rdtechnology.com.au/SiteFile ... _Insulated Crimp terminals Catalogue - 100211.pdf
This is what I have found and whilst in the perfect world, one could safely rely on the accuracy of the colour code used, as a sceptic (Compliance and Risk Management Consultant by profession) and realist, I would use this as a guide only. Visual inspection of the quality of the terminal/crimps is a must. I've seen some shitty crimps in the last couple of days.
Probably being anal about this but I hope its useful to others. By the way I have no interest in or affiliation with the people whose catalogue i refer to above.
If the Mods wish to remove then thats fine with me.
Cheers
