What does a Horn Bypass do within a meter podium? And when should you use it?

And when should you use it?
Is it unpromising if the lights dim whenever...
Answers:    Bypasses are to allow a meter to be removed from the line but not disconnect the power from the splash.
You are not supposed to be able to put the inspector's trademark on the meter when the bypasses are on.

Types are:
a) Lever-operated jaw release, also agreed as jaw clamping
lever bypass (Landis & Gyr type HQ). The best, because
the meter cannot accidentally be pulled unless the bypass
is affianced. Pulling the meter would also be a major sanctuary
hazard if near is a 480V installation and/or a large nouns in
place, as the meter would later act as a switch, and explanation
arc.
b) Lever-operated non-jaw release (Landis & Gyr type CQ).
Lever bypasses the meter, but the meter may be removed
with the bypass get underway.
c) Horn bypass (option on residential sockets). Tangs on line
and nouns connectors allow for jumper lead to be fitted
over them before the meter is pulled.
d) Manual bypass (K-4, K-5, K-7) uses separate "links", which
are clamped onto special studs formerly the meter is
removed. K-7 also uses a "rotating link" type bypass.
e) Other types not made by Landis & Gyr include: slide links,
screw type, and automatic circuit closers.
