What Kind of Plug is This, Anyway?
The AC plug on your new 20 Amp Furman product is a NEMA 5-20P. The blades are oriented
perpendicular to each other to distinguish the 20 Amp plug from the more familiar 15 Amp
plug, the NEMA 5-15P which has two parallel blades. All products that are rated for 20 Amps
must use the perpendicular blade plug to obtain a UL (Underwriters' Laboratory) safety listing.
We recognize that using an unfamiliar plug may be an inconvenience to our customers, but this
is a matter of public safety.
So where do I plug in the NEMA 5-20P?
Devices with a NEMA 5-20P plug will require a 20 Amp or higher rated circuit. Please notice
NEMA 5-20R receptacles have one T-shaped contact that can accept either the horizontal
parallel blade or the vertical perpendicular blade. According to the National Electrical Code, if
one wishes to utilize loads in excess of 15 Amps, the electrical wiring, circuit breakers, and receptacles must
be rated at least 20 Amps. Locations without 20 Amp receptacles should be inspected and upgraded to the
proper NEMA specification by a licensed professional. The NEMA 5-20P (Plug) is designed to be used with a
NEMA5-20R (Receptacle), pretty simple – right?
Is there any alternative?
Yes! You may adapt the NEMA 5-20P to a 15 Amp outlet with the intention to draw no more than 12
15A outlet 20A outlet
Amperes continuously. Furman has designed the ADP-1520B in compliance with UL specifications just for
this purpose. Please contact your Furman dealer to verify the ADP-1520B is right for your application. In a
15A outlet 20A outlet
business location, a local fire inspector may not allow the use of adaptors deemed noncompliant. The safety listed ADP-1520B would be a
worthy consideration in such instances.
The ADP-1520B is UL and CSA compliant.

OK, suppose I use an improper adapter with a 15A outlet and then I draw 20
Amps anyway. What will happen?
Probably nothing serious, since most commercial and many residential circuits are at least 20 Amps. However, some residences do
use 15 Amp circuits; if you attempt to draw more than 12 Amps, the circuit breaker on the ADP-1520B will "trip". In order to avoid this
inconvenience, check the electrical service panel, locate and confirm the size of the breaker installed, if the 12A breaker trips reduce the
load to below 12 Amperes. Avoid repeated nuisance trips which can result in damaged equipment or in extreme cases fire. Note nuisance
trips can be an indication of electrical faults in equipment or the electrical system, yet usually it's due to high current draws
