Frequently Asked Questions
Which lead does a given vehicle need?
The one that matches its inlet.
And the unit's socket at the other end.
The inlet was fixed by the sales market.
Alternating and direct current use different contacts.
The workable combinations are few.
Is a portable lead from a wall socket acceptable?
As an occasional fallback only.
General sockets are not built for hours at load.
The lead limits current for that reason.
Old wiring and worn outlets overheat.
Daily use belongs on a fixed unit.
How long should a lead be?
Long enough to reach either side.
Inlet positions differ by model.
Front, rear and both flanks are all used.
Excess cable is a hazard on the ground.
So the answer is generous but not maximal.
Why do leads fail before anything else?
Because they are handled and abused.
Dropped onto grit.
Driven over at the kerb.
Bent hard in cold weather.
The conductors break long before the electronics.
Do coiled leads have a drawback?
They carry less current than they look.
A coil holds its own heat.
That forces a derating.
They also fight the user in the cold.
The benefit is that they stay off the floor.
Is connector theft a real problem?
On unattended public sites, yes.
The copper is the motive.
Locking holsters and cameras deter it.
So does lighting.
Spare leads keep a bay in service afterwards.
Can an adaptor bridge two standards?
Rarely, and not for direct current.
The communication signals differ.
Safety interlocks refuse the connection.
Some alternating current adaptors exist.
They are not a general solution.
