The small car is still on.
I use a Europa Plus which came in a carry bag (over shoulder). In that I have everything I need for a days testing in an office. Tester, Earth bond lead, IEC lead, Cutters, x point and flat screwdriver, several fuses, 3x13A plugs, 200+ plug top labels (also some cable wraplabels, Visual only, fail, microwave), pen, bar code reader, microwave tester, IEC to Clover-leaf adaptor, serial lead (just to keep it handy). laminated copies of:- Training Cerificate, Cal certificate, bar codes.
The above slings over my shoulder, so easy in a car. I also have a crate which has the following 13A to female-x and male-x to IEC. x equals:- 16A commando, 32A commando, 110v Commando, Powercon, More 13A to IEC.
My main box of labels, Code of Practice, more 13A plugs. more fuses.
The crate sits in just about any car boot.
